Early 2011 MBP 15-Inch Selling Price?

[S7Kep]

I plan on selling my current Macbook Pro and then upgrading to a new Retina MBP or save some money and get a MBA and build a PC with the money I save. Just out of curiosity( I am going to school for Software Engineering )

Should I get a MBP Retina or MBA?

Anyway,

Specs:

2.2 Ghz i7
8GB Ram

128GB SSD as boot drive
750GB HDD as secondary
No CD drive but is included

Triple Boots into OS X Lion, Windows 7, and Gentoo Linux.
Adobe Photoshop(Mac)
Adobe After Effects(Mac)
Adobe Premier Pro(Mac)
Microsoft Office(Mac)

Has AppleCare until 2014

What kind of price realistically can I expect to get?

As a starting point, you can check Mac2Sell, eBay, or Amazon for prices of similar models, to get an idea of what you may be able to charge. Then adjust your price to account for condition, configuration, remaining AppleCare coverage (if any), etc.
