Obviously you'll never get back with you "invested" into this hobby but $450-$540 is a pretty safe guess. If I was going to sell it, I would clean everything up and try to get good clear CLEAN pictures. Get everything organized and take a picture of everything thats being sold. Thats might bring $600+

Another options is to find someone locally and do a trade for something else.

Why not just keep it tho vs having people nit pick and haggle about the price?
