well what i was intending is a general guide to whats good and what not to touch with a big stick.

If someone is on the look out for a cheap synth they can programe they can look up this guide or if someone wants an analogue synth with midi and can't afford a new one look at the guide. It more that kind of thing thats missing, i know some of the thing that might recommend should be in a museum but they can still be used
