brushless ESC to work with HV4.5, 6.5

[Gee]

I have a (2) 4.5 and (1) 6.5 novak motors. Will be running it in a e-maxx with 2 2s2p lipos. I'm looking for a controller other then Novak that will work good with these motors. Something that can be use with other motors as well, more volts, expandable. You know faster! With the Novak ESC you at limited to their motors. Somethng around $200.00 but all suggestions will be appreciated.
