Haha, $900 is pretty pricey to me, particularly when customs shove the price up over the $1000 mark just for the chassis. By the time I get the truggy shocks, esc, bodyshell, digi receiver, motor, wheels and tyres and lipos it's easily going to be a $1800+ build.
Hmmm 68mm is pushing it, I think I'll wait till the lipos get here to see how much room I'm gonna have left. I know they use the full length of the battery tray so if they are tall enough to stick out the top of the tray i'll be limited to 60mm motors.
