Another RTR buggy to keep your eyes on is the HPI D8S (
http://www.hpiracing.com/kitinfo/106116/). It's based off the Hotbodies D8, so it'll likely be a good starter racer, without breaking the bank. It's got a 0.21 pullstart engine and a basic 2.4 GHz radio system. It's going for $460 on Amain, so that's a heck of a deal for a ready-to-race 1/8 buggy.
