Picked up one of these this week:

... mostly because I'm scared to spend the money on what I really want:
and wanted to start out somewhere.
Who else has the fever? I almost considered picking up a soooooper cheap used Roland R-8 as well. Ae used one, so hey, it can't be all bad, even though the built-in PCM sounds are pretty crap. It's one of those ones you need "ROM cards" to expand the palette with, though. And that is totally gay.
A synth might be a better option, but... everything out there (that's less than $500) seems kinda disappointing. I know TWH loves his MicroKorg (or used to), so... what pieces of sound-generating hardware have you known and loved, and possibly still curl up next to on a stormy night? sqrt, this is your opportunity for an entertaining MC-303 story. Saw one of those, too, btw, but $150 was a bit much to go for on nostalgia alone.
Lust with me. You know you want to.
