outrunner for Revo on 4s ?

Hey all. i'm interested in giving an outrunner a shot. Are there any inexpensive outrunners with KV's close to 2k that will be heavy enough for a Revo ? I'm only running 4s, so I'm sure that limits my outrunner options immensely. I used the motor selector and determined I need a KV from 1800 - 2200 or therabouts. If it's a bit lower KV, I can always gear up a bit I suppose.

Any ideas ?
