How much do you think I can sell my SP2 for?

So I have a lightly used type cover 2 and a brand new sp2 (256/8gb) and am trying to sell it to finance a surface pro 3 which I've preordered. I've had it listed at around $1100 for the past few weeks and thought that being a new device with a keyboard that it was fairly reasonable and undercutting most of the other ads on craigslist in my area. Now that the Microsoft Store and futureshop has put the sp2 on sale (my guess is it'll be the new price point) of $1100, I'm wondering what you guys think is a good price to put it up as and at which point you'd give up on trying to upgrade.
