It's an Apple MacBook 13.3 Screen 2GB Memory 250GB mid-2007 model. It's in excellent condition as well. Looks like I can get $160 for it at Best Buy.
It's crazy how cheap they sell for when i bought mine it was 1100$ I want to sell mine as well and its in great condition but i dont think i would sell it for less than 500$
My MacBook was about $1,200 new, and now it is probably worth $400 at most.
I just sold an alum MacBook today on eBay for $435 (C2D, 4GB RAM, 160HDD). A bit off topic, but you're accurate in how much your machine is worth
Edit: As a matter of fact, now that you've installed 8GB RAM you could probably get closer to $500 for it. Personally, I am not getting rid of either of my alum MacBook's (not saying you're trying to sell yours either). I really like them. They have been nothing but great for me, minus a few minor problems that were an easy fix.
I've been able to fix my little problems. My next purchase will probably be a MacBook Pro 15" (probably not Retina) with the 1GB card in it, or whatever the best at the time is. I'll do the RAM upgrade myself, as that's easy. I just hope Apple doesn't do away with the Pro 15" with the Superdrive, or with user serviceability. That's what I love about my Aluminum. Easy to service myself.
