I would start buy going to WWW.Speedtechrc.com
They don't sell junk!
My suggestion would be
Yokomo Special Edition
Or RC Lab 7 Even
I personally have an RC Lab Seven Even and love it.
Integy Motors probably get you the most bang for the buck. Those are also available at Speedtech. Never heard of Integy? Well, they buy your favorite Mod and stock motors and then tune them. Matrix motors can be tuned P2Ks and MVP motors etc etc.
I love my Hi-tec Lynx 3D FM. There were a lot of guys racing at Ripon with the 3D with Spectra. Then they don't have to change Crystals.
Being from Canada, I would be tempted to go with the RC Lab Seven Even car, because there is a really cool group of Canadian guys that race them there, and would be able to give you lots of tips.
Here is a photo of my RC Lab Seven Even Pro 6.0
Compare the prices off the Yokomo, XXX-S and the RC Lab when it comes to initial cost, spares and upgrades.
