That Tamiya TLT might be a good bet, or even a stock Clodbuster, if he wants to go a bit faster, take a look at the RTR Losi truck. It's a good deal and comes with a good name-brand radio. Here's the link: http://www.teamlosi.com/kits/XXXTRTR.htm

Crawlers can get pretty pricey, and are built for one purpose.

Whatever you decide, your best bet is probably a RTR for someone new to the hobby..
