I currently have a Oak Classic D whistle. I’m looking to buy a cheap C whistle, but not certain which whistle would best offset my Oak and give me greater variety between the two. I’m mainly looking at Clarke’s Sweetone, Meg, or a generation whistle. (I do, eventually, plan to buy a more expensive whistle, but right now I’m only looking to spend around ten dollars) My Oak has a bit of a raspy buzz in its sound, mostly in the higher register and when I’ve been playing for a while. I haven’t had enough experience with whistles to know if this is simply the sound of my whistle, most whistles, or lack of skill on my part.
I know what sound people prefer is mostly a matter of opinion, but I’d be interested in what y’all have to say 
If you can’t make the step up to a Jerry Freeman tweaked Gen, I have to say that the new Feadog Pro in black or nickel really surprised me. It’s about twice the price of a normal Feadog but it’s the best untweaked (is that a word?) inexpensive whistle I’ve played. In tune with itself and a much heavier more substantial tube with a little more attention to the mouthpiece after molding I’d say. I think it’s a better choice than any of those you’ve mentioned. But, as always, YMMV. IMO the Sweetone is not bad but it requires some real attention to breath control which might be difficult for a less experienced player. I know it frustrated me as my first whistle. Jerry Freeman fixes these too.
Good luck,

“bit of a raspy buzz in its sound, mostly in the higher register and when I’ve been playing for a while.” - when that happens to me it’s moisture buildup.
Ditto the moisture buildup. I also second the motion on Feadog although I personally don’t think the Pro is worth the extra money; I couldn’t tell any difference between the stock brass Feadog and the Pro. You’ll find the Feadogs and the Gens need more precise breath control than the Oak and that’s a good thing.
The Feadóg Pro (nickel) has a heavier gauge tube than the standard Feadóg. The heads are identical.
Consider the Jerry Freeman Mellow Dog (D) plus the C body. The package is a bit more than the $10 you quoted, but if you can go a little higher, you’ll get two whistles that sound good through their range and play in tune.
Hm. Thanks for the advice. I may go with a feadog for now then. While I could step up with my price range, I want to wait several more months until I’m more experienced before laying down an investment.
I don’t think $40 for a whistle qualifies as an investment 
If it’s just going to be a few months, I don’t see the advantage to waiting. If it would be 3 or 4 years, and if you really wouldn’t buy any other whistles in the mean time, then that’s different. The Mellow Dog is a Feadog with a re-worked fipple, btw. It’s neither shrill nor breathy.
But whatever – it won’t hurt my feelings no matter what you do. I’m just passing on a little of my own experience – a box full of cheap whistles that won’t be played again now that I have the Mellow Dog combo.
Referring to the original post, if “greater variety between the two” is still your parameter then the Clarke is the answer. The Meg and the Sweetone are very similar, my C Sweetone is in a slightly heavier gauge metal than my D Meg. Being conical, both whistles sound very different to any of my parallel-tube whistles, some of which have their own distinctive characteristics, but none sound like a Clarke.
If variety is what you want, get a conical-bore whistle - at a budget price a Clarke is probably your best choice. From an aesthetic viewpoint, I prefer the “plain-metal” Sweetone to the (usually cheaper) painted-finish Meg (which does scratch easily), but I enjoy playing both - YMMV, but at the price, it’s not a great loss if you genuinely don’t like it
I’d like to second highland-piper if you can make the reach. There’s not a better performing whistle to be had under $90 than the Mellow Dog. And it is much easier to learn on because it is so consistent. I think the D is about $38 and the D/Combo is about $10 more. For a light-years better performing whistle in every measurable way. While statements are absolutely correct about Clarke’s being a completely different sound which some prefer, they will drive you crazy with their subtle breath requirements. Don’t get me wrong, I play them too but they’re tough and discouraging to learn on, in my personal experience.
Jerry’s Ebay store currently has a D/C set for a “buy it now” price of $41.50 + $5.55 shipping.

According to the listing he ships “worldwide” but I’d expect somewhat higher shipping to France.
Clarke C’s are, in my experience (more especially, Sweetones), some of the worst as far as being in tune with themselves. The only difference between the Feadog and the Pro model is the gauge of tubing, heads are identical as far as I’ve seen. Feadog’s and Oaks are both good instruments. I prefer the nickel but the brass Feadog is fine as well. Generation C’s will give you the most trouble when trying to make them tunable: the heads are too small ID for the OD of the body and therefore often crack if you don’t take steps to improve the fit. With the Feadog as an option, I don’t think it’s worth the extra effort.
