I think you completely miss the point here - it's got nothing to do with   
cost as most engineers/tech's build for building sake to satisfy   
themselves, because *you* think it's a crap or expensive idea doesn't   
mean others can't obtain something from it.

Did Bob Moog say - "I'd love to design a synthesizer, but, I haven't got   
the money right now"?

This list is entitled "Synth-DIY", not "I think it's a crap Synth   
idea-DIY", "You need $$$$ to build a synth before you start DIY" or "I'll   
approve your ideas synth-DIY". Give us a break.
