Greetings, Have you thought of building a kit from PAIA (www.Paia.com) or Blacet research (http://metro.net/blacet/music.html#Products) or a modular analog synth (Synthtech.com). I highly recommend it, it is a good "education" to do and you can enjoy the fruits of your labor!!. There's help here and from the kit manufacturer if you need it.
