Tmaxx or REVO?

Go for the Revo. Better handling. More durable. Easier to tune. Easier to fix. Better performer in every category over the tmaxx. I own 2 tmaxxs and they are the big pain in the a$$. To fix anything on the tmaxx you have to do some major diassembly where as the revo looks alot more user friendly, especially for some one new. If you can't afford a revo you will be happy with a tmaxx... until you have to fix it. Then you are going to hate it.

You should also look into the Savage as well. Very powerful, very very durable. It won't perform as well on the track because it isn't very adjustable, but if you plan to do some major jumps, the savage is the way to go.
Conclusion -

If all you are going to do is bash get the Savage.
If you plan to bash as well as race get the revo.

If you can help it DO NOT GET A TMAXX!!! Their good trucks but there are much better options for the price. Hope this helped.
