>>On EBAY I found a set of Victor 883's for $175 for a set of >>2....they do sell. (The guy put BATTLEBOTS in the title, but >>whatever sells them)
Those were probably not the 883's you guys have laying around.
Check out
http://www.ifirobotics.com . That's the non-FIRST (ie BattleBots) side of Innovation First. They have a 24V Victor 883 that is rated at 60A.
You're right though, the BattleBots folks will buy the old 12V 883's--the lower weight classes robots (30, 12, 2 and even 1 lb) are getting popular.
