Looking at your signature thing looks like your in Aust.
I too have been looking at the himoto/hispeed/atomic cars. You get a whole range of opinions ranging from there a complete waste of money to these are some of the best value kits around. I will reserve judgement until I see one actually running.
But in the meantime, if you are in Aust, do a google search for plaig rc. I've never used them personally. But looking at the site and their forum they are local and seem to stock a lot of parts for himoto/hispeed/atomic and have had some good feedback. Pricing also seems reasonable
