You mean Reason 2.01
Reason is cool, but to use just for drums? That's overkill.
Also, I think that a VSTi is easier to use in Cubase or Nuendo than Reason via Rewire.
There are some more that are nice:
FXpansion DR-008
Linplug RM III
Steinberg LM-4 and LM-4 Mk.II
Waldorf Attack is a great drum synth
