A-Tech Mini Monster/Leo X/Venom Mini Giant, $120 for truck and controler, It's got solid axles fro and rear, slipper clutch built into the trans, I use Losi Mini-T batteries and charger for mine (I've got a couple of those too, but they're only 2wd) and a few mods to make it better at crawling. It runs off of AA's but I recommend a battery packYour LHS should be able to get it through Schumacher America or HRP (
www.a-tech.cc and
www.racing-cars.com )
Duratrax Mini Quake, $190 or so, Not a Duratrax fan at all, but this one is one of their better products. It's set up more like a touring car with 4 wheel independant long arms and big tires, it also comes with a pack and charger too. It can bought at your LHS or Tower Hobbies (Great Planes is the parent company of Tower Hobbies and Duratrax as well as a major hobby distributer world wide) (

Hot Bodies Mini-Zilla, I think it's in the $160-$190 range (can't remember for sure, sorry) It's also a 4 wheel independant design, but is set up more like the HPI Savage (and I think it's sold as one in Japan). I hear A-Tech Mini Monster oil filled shocks shocks are a good upgrade (almost manditory) for it. (
www.hotbodiesonline.net should be able to get it through
www.towerhobbies.com and
www.horizonhobby.com as well as your LHS)
Associated Electronics (
www.rc10.com) sells the RC-18T and MT and those are around $190 for the 18T (can't remember what they want for the MT, but it's close.) These trucks are also 4 wheel independent, and are well featured for the money. I strongly recommend the aluminum outdrive collars or MIP aluminum outdrives since the truck has a habit of spitting out dogbones without due to flex in the plastic outdrives. You should be able to get them at almost any of the sources above as long as they aren't on backorder (so fair warning)
Tamiya TLT series (
www.tamiya.com) those are about $170 new and are the only other ones that are solid axle and can use normal sized (1/10 scale) radio gear and electronics. These have also become pretty popular as scale rock crawlers and 4X4's using 2.2" wheels and tires with a wheelbase extension (also give the truck a much needed boost in ground clearance)
All of these trucks are 1/18 scale and all but the TLT's are available as ready to runs, and some you can get as Almost Ready To Run or Kits, while the TLT's are kit only, so they may not be the best for your buddy. Good luck and happy hunting.
