I’m a Highland Bagpiper, and I’ve always wanted to learn uilleann so I looked around and found a website that listed makers, so I looked around and found that David Daye pipes were the cheapest. I was wondering if it is because he is just a nice guy, or not a very good pipe maker. I would just buy a 3/8 or half set by him becuase the price is so good. Thanks for your help!
I can’t comment on his drones or bags or bellows, but i do have one of his chanters. It is a quiet nice chanter to learn on. They are consistent, which is good if you are trying to learn. They are also good for the price. I since have recieved different blackwood chanters and i still have the penny-chanter because its a good instrument. The only problem is that its not made of wood. Instead the inside is made of brass. There is some difference in sound from a wood chanter, but there will be plenty on time to spend alot of money on a nice wood chanter. Also, dave is a really nice guy. If you have any questions you should shoot him an e-mail. He was really helpful to me.
I have a Daye half set that I am very happy with. I purchased the drones and chanter from him and built my own bag, bellows and connectors. What the set lacks in aesthetics it more than makes up for in playability. In my experience, Dave is a bona-fide nice guy to boot and is very willing to help. At some point I will upgrade to a more traditional wood set, but not before I get to a more advanced level of playing.
'Got to agree. I like my chanter. I’ve had it for a couple of years now, and the reed still behaves. Does he make a flat chanter C# or C ?
Know little about UP’s but I believe that Mr Daye indeed does make C-chanters.
Take a look at his homepage:Uilleann Penny-Chanters
I consider to buy a Daye half set myself!
Now that be associating too closely with your pipes! You do need an identity of your own! 
I have been extremely pleased with my Daye half-set. His drones have a fullness lacking from some of the more traditionally made drones (not all, but some). I think his experience as a Highland piper has helped him develop a very full and robust drone sound that still rests nicely behind the chanter. As a long-time Highland piper myself, it is important to have a rich drone sound.
david daye is a nice guy, matter of fact.
The price has to do with materials and the time it takes to build, I believe.
