RE: T4 on Ebay
Nice truck! You'll have to cross the right person at the right time to get your price out of it on eBay, but I wish you luck. If it ends without a bid, you'll be able to get a ton more money out of it if you part it out.
SS5800's are going (used) for $180 or 190, you can get $15-25 per body, about $10 per battery, $10-20 for a set of wheels w/tires, $5-10 for the servo, $40-60 for that radio/receiver, and you can 'nickle and dime' all those chassis parts separately for a pile of money. I do it all the time - buy a complete vehicle or roller that I may need one part for, then I part out the rest and usually make money by getting parts that I want/need!
