well i'm thinking on selling the 1013 because the 2015 is so damn awesome! I love the 1013 but a carve that takes 10 hrs the 2015 does it in 19 min. i've learned vcarve pro toolpathing and the tiling system and let me say its amazing!!
I have seen them for sale in the $800 to $1500 price range, actual value likely to be in the middle of that range with 1500 being a bit out of the park considering that I paid 2099 for mine brand new and that it is a discontinued model.
i wonder if there is a parts market, I've always thought that I'd wait till mine died then break it down and sell the parts on ebay. Considering what you can get for the motors, and motherboard, that might make more money..........you'd end up with some to throw away and it would take time.
