whoever wonders shit like this needs to READ, and browse this site. the resources forum - looking for sounds thread is FULL of sample sources fools peep it and get off ya lazy ass and do something with it. you want drum breaks or old vinyl drum breaks, i posted a link towards the end of that thread to a site FULL of all those old classic breaks and THEN some. (literally HUNDREDS to find on there good ones too)
i have dowenloaded alot of these breaks and sliced m, and have found DOZENS of good links to single drum hit samples (among many other type of samples) in just that little thread alone. personally atm (due to what the above mentioned) drums and drum samples are the last fucking thing im worried about.
( i wouldnt know about kits, dont use kits myself, i do what all the people above said, which i recommend you do as well)
peace
