Slate Drums are excellent for rock style drums and many people love hooking up the edrums to trigger the drums. For all around sounds the SD 2.0 is great and works with all the EZDrummer expansion packs. If you can hold off for a few days you can get SD for an incredible price (check our site in a day or two). ***Edit - Superior Drummer 2.0 now on sale for the month of September for only $149*** (visit our site for more details)

I would check out the CME 88-Key Master Keyboards, it's the closest thing I can think of to what you want.
