Stand alone recommendations?

Just gathering some more info! Any suggestions on which stand alone I should be looking at for the 250+RWKW power range? I don't have much knowledge on the tuning side of things. So any help would be great.. Heard good things about the Apexi Power FC, thoughts? 

Let me know what you guys are running and what power you are putting down.. Any problems you've run into. Things like that!

Cheers!!
