Best places for drum sounds, rolls bass sounds and samples

I know that this site is supported by selling these sounds but is this really the best place to get sounds? I am lookin to build a vey large llibrary for my New 2500 and Ive seen MPC sounds everywhere including E-bay. I want to get quality and quantity for my money and I would love some of you experts opinions on which kits, comps etc that I should go get, there are just too many.
Drums, drum rolls, build ups, breaks loops and great bass sounds is mainly what I want, I can find my own samples.
Also, I would like it if I could find some of these in program form(just makes it easier to get started).

Do a google search for FREE SOUNDS, Bass sounds, Drum sounds, Free Breakbeats etc....... You'll find at least 40 websites with FREE sounds---I did.

Or if u want to go the ebay route-----then this cat with the id named malicetrk16 has the BEST DRUMS on ebay.
