Associateds and the like don't fetch as much on ebay as the super-collectable Tamiya's - but i think what you've got there should fetch a pretty penny (if it is truly mint and complete) - as a guess, between $150 and $200
Thanks. I'm not sure I would sell it right now. I had one of these in 1986 and raced the crap out of it. It's kinda nice to have another one around. I'm not sure I can put it on the shelf and look at it though. I keep thinking "I wonder if it will handle like I remember?" "I gotta get a MIP transmission!"
It would be a shame to put a scratch it though. I'll fight the urge a little longer.
