depends on where and how you are selling them...if you look on ebay they can go from anywhere from 150 to 200 bucks....but no one is buying them at that cost...you could throw them up on ebay and see how much they get at auction. or I would put them up on craigslist at 100 each and see if you get any bites....I am in the same position as you..I have 2 285s right now and I am going to upgrade here soon so I might be selling one of mine off eventually we will see
