You mean PAiA? (
http://www.paia.com/p9700s.htm) - thats the one i built.
It could sound good also, its broken now - when i started it up and where making a small patch it said "click" and then it started to smell burning electronics.. I found what parts are damaged - to much for me to ever bother to fix it.. or maybe not i dont know.
Otherwise why dont you start to build your own hardware effects? its alot easier than building a wholesynth, and its pretty nice to have an moog-filter copy and so on
