If you are after boombap kind of drums then I can recommend the following drum kits.
Boombap drumkits:
M-Phazes Dirty Thirty 1
M-Phazes Dirty Thirty 2
Boonie Mayfield Kit 1 *
Croup's Filthy Drums
Deadly Drums 1-3
Paul Nice's Drum Library 1-5 **
* Boonie Mayfield = Boon Doc from Youtube.
** Vinyl. Contains breakbeats only, so you need to chop them to get one-shots.
All of the aforementioned drum kits are excellent and can be found on eBay. They are all boombap and have that raw, gritty sound. Best of all, they are cheap.
I don't know what to recommend you if you are looking for "clean" drums.
I will however recommend to you that you at one point start sampling your own drums from vinyl. With the combination of dynamics processors such as PSP VintageWarmer and Bootsy NastyHF/NastyLF you can really make some ill one-shots.
Hope this was helpful!
PS: If you want to learn about classic breaks then visit
http://www.mhat.com/phatdrumloops/ but
don't use samples from that site as they are lo-fi and because it generally just sucks to use breaks downloaded from the web.
