My pipes were made by Colin Ross and cost me about £450 (but that was in 1983!).I'm not sure if he is still building and selling new sets, but he is certainly still servicing them. Check by sending email to rosspipes@aol.com or ring 0191 252 6585.
The Northumbrian Piper's Society was advertising an "Absolute Beginners Weekend Course" in Whitney, Oxfordshire last March where instruments were provided.
I suggest you ring (Dave Shaw?) 01865 714778 to see if the excercise might be repeated.
Cheers,
