Tons of quality name brands to choose from... Losi, Associated, Mugen, XRay, Serpent and then my personal favorite is Tekno.

What I feel sets Tekno apart from the others is their durability can't be beat, performance is on par with XRay and Mugen, and their team driver support is right up there with Losi and XRay. What Tekno offers that nobody else has is a lifetime 50% discount off any broken parts mailed into them with no questions asked making Tekno the least expensive brand to maintain. Tekno parts also tend to wear less quickly than most other brands and their design offers one of the quickest/easiest to perform maintenance with least amount of hardware to remove to quickly service diffs and common hardware to reduce time swapping bits on your driver for faster service time.

As far as selecting a class goes, if you're not into racing and just want to bash around than nothing beats the MT410:
