Darn, I uploaded the wrong MP3 last night... (was a little buzzed on good ole Sam Adams.) I put the right one on now, so you can hear a little of what my roland jv1010 can do...
Anyway, my point... my cheap module that sells for $200 - $400 dosen't sound half bad, does it? If thats good enough for you, you might be able to save some bucks that you can use on other gear.
Now if you got a recording contract or something good going on, you might want the best. But as a newcomer to keys, might just want a decent cheap unit to learn on... then when you outgrow your first board you can move up to a Triton or Motif.
Kinda goes against the buy cheap buy again theory... but then again keyboards that used to cost a few thousand are now less useful than a $199 casio... the same will be true of the triton.
