Those Walmart crawlers are ok for what they are but I think Oizarod115 is looking more towards a hoddy store type r/c truck. There is a big difference. The type he is looking at you can change the body, throw in hopped up engines, change tires, upgrade shocks, heck I even put a rear locker in one of mine. There is a huge aftermarket following on those types of vehicles.
Also he is looking for a Nitro R/C which means it has a 2 stroke engine that runs off a Nitro methane mix instead of batteries. They are a blast and will reach speed of around 50 mph.
There is one thing to remember though. They are lots of $$$ and much like a JEEP, they will empty your wallet and bleed you dry. :D
Here are a couple pics of one of my 1/8 scale trucks.....
