The Hot Bodies 10th scale stuff is a good buy for the price. They are on ebay brand new for about $220. I would recommend the Hot Bodies 10th scale and 8th scale stuff. I have a Hot Bodies Lightning Stadium Pro-R Truggy and I love it. The hb 10th scale stuff is built very durable just like their 1/8th scale stuff. They include .15 engines which can also be upgraded to .18's too.
