RE: Brushed vs Brushless
Another option you might look at is to go cheap on a esc motor combo to learn with. Look online for a tamiya esc and a silvercan motor to get it going and have a good time with. Gear it low for torque and you won't trash the truck before you learn. To drve and set it up. 20 30 bucks or so, then keep it as a spare set and go goofy with brushless power. Traxxas xl5 can be had for cheap too.
