I hope you have many happy hours playing your Feadog!
And just to throw in my 2 cents:
To each his own, but IMO inexpensive is the way to go. There’s a reason why one of the names of the instrument is pennywhistle. Can’t see layin’ out a lot of cash for something with that name. 
I personally prefer to call it a pennywhistle, but, others cannot tolerate the implication that its something cheap. It is what it is. Its the WHOAD that gets you deep into your pocket$.
Pennywise… Pennywhistle is way to go…
Call it whatever you like… just have fun.
It’s a great thing: to take an inexpensive instrument and play some of the most beautiful and lively music with it. The world would be a better place if more people played music. Hopefully more people will learn about these instruments and play ‘em, be it ITM or whatever. Looking forward to grabbin’ the sheet music and playin’ Christmas tunes again this year.
They’re pretty durable little instruments too. (To keep my train of thought somewhat in line with the OP. It does tend to jump the tracks a bit. 
)
Great! You got one. So now you are a whistler
i AM curious, so please let me know how you like it after you did play for a while, some days, weeks or so
He, he how to call a Whistle, Penny, Tin, …or whatever … some weeks ago i did have my own thoughts about that and wrote them down
read it here: whistles, penny tin or what do you call them?
Comments and your thoughts about it are always apreciated
By the way, that lead me to another question. How do you call yourself? Whistler, Whistleplayer, Tootie the Tooter, …?
(that might be a title for a new article )
NEWBIE
Newby of what thats the point
UPS says I’ll get my feadóg on tuesday, but I was rather anxious and there was a Clarke Celtic D with free 2-day shipping…so I got it on Friday. I’ve been playing it much more than I thought I would, and I’ve found it’s not too hard to transition from my other instruments b/c I already developed good breath control and can sight-read music.
I’d love to hear back from any of you who have also played this model. I can get what I imagine is the best tone I’m going to get out of it, but the upper register is a bit iffy past B.
To those of you still recommending the Freeman’s and Susato’s, I know I will eventually acquire one, because I’d love to have more whistle sounds for different styles and moods I may be in, but one whistle at a time, eh?
As for discovering if whistling will become a lifelong practice, there’s no question. Something about this style of music strikes a chord in my soul; it always has. I feel it’s really connected to my love of the outdoors, which may be more of an obsession…but anyways.
thank you all for your input and advice! great to know that I’m not alone in this whistling world
