I have a 4-month old MacBook Pro that I'm trying to sell but have no idea what a fair price would be. It's the current model, MC725LL/A which is the 17" MBP with i7 Sandy Bridge processor. Ram has been upgraded to 8GB. It has the 750GB standard HD. Standard glossy screen. Comes with OSX Lion that I purchased after I bought the laptop. It's in mint condition and has barely been used. Comes with all packaging, cables, discs, everything. I don't want to try to extract every last dollar out of the sale, I'm looking to sell it QUICKLY but don't want to get ripped off either. Any advice would be welcome, thanks!
