Drum Libraries?

Hi,

I am new here. I am producing rock/hip hop tracks and need to know if anybody has used any of the pro speciality or hip hop drum libraries for the MPC 4000 ie. the Beat Producer Series or Crunchy Kicks and what you think of them? Also, can you get them on hard copies (CD/DVD) and where can you get that?

Thanks!

Theres a megadrums one which has loads of drum machines all in akai format, thats a nice one for having all your 808s etc. all done for u.
