I'll give up RC before I go brushless.. I just think they're that lame. The thrill is gone, however fast they might be. This is a motorsport for me, and the smoke and screaming sounds are all central parts to it. Period. Just my $.02 of course...

If money is no issue then just get the OS Speed.. Long lasting, easy to tune, gobs of power... There are just so many options out there.. Again though, I would get the JX Ninja... Just look at in the Mugen truggy..:

In a buggy it'd be even faster...
