DD Savage help

I've been tossing around converting my savage to brushless. I would like to use an outrunner and make it a direct drive setup, but I can't seem to find a n out runner to do the job. I think a Scorpion outrunner would be my best bet, but my buget is kind of tight. I think the most I will spend on a motor is going to be $100. I'd like a motor that would be kind of cheap so I would have more money for other parts like better diffs or maybe another Mamba Monster. Does anybody know of anywhere I could find a motor that would fit my buget? If so Do you have a link? Thanks for any replys.
