You might be interested in a Moog Prodigy
Ive seen one on sale in a music store in
New Orleans(unfortunately i cant remember
the name of the store) for around $900.00
It all depends on your budget. With the analog craze going on right now, these
synths can run you a pretty penny. You might be better off with a kurzweil. It comes
with factory preset Moog sounds as well as tons of other features. Its not the true analog sound you get from the real thing
but I think it comes in as a definite second.
There are also plenty of Moog and other
programs for kurzweil that sound almost
if not just as good as these vintage synths.
