Oh yeah...I forgot about the 303 speed. I think I have borderline ADD, so its slow enough to mess with my creative process. If I never had a 404, I probably wouldnt have gotten so spurled. I will say, I will never sell my 303 though. Too classic. The only other pro I can think of for the 303, now that I think about it, is the ability to resample white using the external ext.

Anyway, I recommend the OG 404, because used they are significantly cheaper than the SX and I dont think you are getting much of a benefit for the price difference. I bought one for $200 on craigslist and have seen more on there for near that. I dont use the pattern sequencer either, so fuck a pattern copy.
