Anyone know of any places to get good, fast parts?

I'm thinking of getting a Magnum. But I don't want to repeat the disaster that was Mad Force parts support (also known as non-existant)

I'm doubting that my local shop will carry CEN, but I will try. If not, I'd like to know of some places I can get hop-ups and such.

If all works out like I hope it will, I might actually get to do some racing. And I think it'd be pretty swank to show up with a Magnum, and whip all the big boys out there.
