I second what chony said. Yamaha and Korg respectively are the best for Jewish Music.

By the way, you said you use a psr 3000.
I believe the newer models; including the mid range psr's (s900 s910 s710) have new drum kits called "Power kits" (2 to be exact). Maybe (?) that's what your looking for.

The korg's pa series (pa500, pa800, pa2x-pro, pa588) have "multi sampled" drum kits, which depending who you ask, may sound better then the Yamaha drums. abit more realistic if you ask me.

Good luck in the choice you make, and feel free to stop by here with any questions you may have regarding the above models!

You may also want to get a drum machine (ex. alesis sr16, sr18) to use via MIDI for new drum sounds..
