Yamaha psr2100 vs 3000

HELP. trying to decide which I should buy.
My old keyboard was a Korg X3 that I never did get to utilize fully (complicated) I am a hobyist interested in creating jazz and Christian contemporary pieces. Is the 3000 worth the extra bucks to a duffer like me?

Hi!
Try posting at General Arranger Keyboard section here.

The extra bucks gets you smart media storage, usb storage/connection to pc, better key feel, mega voices(much better guitars), improved drum samples, improved voice processor, Tyros compatability, color screen, dedicated intro/ending buttons .....

Yeah, i think it's WELL worth it.
