Best sites to buy throttle bodies?

What other mods do you have? If you're still near stock, it wont really be worth the cost. I'd look into putting that $$$ into other mods, like gears, pullies, wheels, shifter, blah blah... As far as the tips go, I got mine from a local exh shop; for the sake of shipping costs and what not, you might be better off going that route. Just a thought...
