I played both keyboards and the VA5 won hands down. The PSR2100 sucked for the following reasons.

1. Crappy Key feel
2. Key size looks like a cheap casio
3. Drums are no match for VA5
4. Choir voices no match for VA5
5. The biggest downfall...The Styles SUCK.
Roland styles are far richer...
6. PSR2100 has great sounds but so does the
VA5.
