I would say that it would depend on what the design is. I got those guys to unwind a Peerless 20-20 of the 40W/10k a-a flavour( the S-265-Q ) and copies are ~$140 or so with better materials. It is *NOT* a very simple wind though.
What is the impedance ratio? is it a plate-voice coil or something else?
Also what did you ask for? I got a moderately priced quote on a similar wattage ( ~10 square inches of core area ) which seemed quite reasonable. I have since learned a bit more and am designing something a bit different for that same project.
Bottom line is that you get what you specify, so make sure you specify exactly what you want. Lots of drawings and redudundancy of the descriptions and call-outs on special details.
they have made lots of stuff for me, and at least one OEM I am aware of. I don't look anywhere else.

Douglas
