If you're serious about some real drum recordings, I might be able to borrow my buddy's drum kit for a weekend... I'll talk to you in IRC sometime soon.
I believe my drum sound from "En Vikingafärd" ( http://www.myspace.com/gurz ) in Gurz is just what you looking for. What can kill the sound of me beating on a beer can with a pen and changing the pitch?
download the drumkits from hell samples. those will serve you well, as long as you spend some time adjusting dynamics so it doesn't sounds like a bad machine.
While your at it, there's an awesome kick sound to be taken from "Edgecrusher" from Fear Factory, and a snare from "Crisis"
... Would I've gotten reps if I were logged in?
But yeah, I don't think it's a big of a problem if you subtly mix it with a second, more prominent snare/bassdrum sound. I got to the point where I don't really rely in rips anymore though, but I remembered making kick-ass drum tracks with those rips
Also, totally go for DKFH cymbals, they kick arse.
