just to clarify, when you say 2s-3s, do you mean two 2s packs for a total of 4s; and two 3s packs for a total of 6s? because you don't want to run less than a 4s in a revo.
i think you should go with a Quark esc, i have one in my maxx and i love it! also i think a xl, lenher 19 series, or a neu motor do very well in your e-revo.
here is the brushless stuff:

xl, lenher 19 series, and neu motors(xl's are on the second page)

you might be able to run the mamba max esc, but it can only run 4s. (with BEC disabled)

and on one last note, you will need a UBEC.
