[WTB] URGENTLY: T520, Maybe W510?

[nano404]

Hi! I've been lurking here for a while.

I've fallen in love with Thinkpads and now I want to buy my first. I can't order from the outlet so I'm trying here. This is my last ditch effort to get the Thinkpad or I'll have to go with the HP ProBook.

I'm looking for a T520, I like the W520 but it's too expensive at the moment. Not sure what a used W510 is going for at the moment but that would be nice. Basically what I need is:

Screen: 15+ inches, @ 1600x900 (I'll definitely take a 1920x1080 if you feel inclined! )
Hard Drive: Not fussy about the hard drive, as long as it's at least 7200rpm
RAM: Not fussy about it either, although 4+ gigs would be nice since I wouldn't have to upgrade it immediately.
Processor : i5 (although, again, I'd definitely take an i7 )
Webcam: Heavily preferred, though if things are slim I'll take one without a webcam.

Max. I can offer is $800 - $850.

BUT I NEED IT TONIGHT. I need it to be in Florida for Monday so I'm trying to purchase it tonight the latest so it can be shipped first thing in the morning. I know private sellers usually offer faster shipping than most online resellers (i.e., overnight) but I don't want to wait so late that I'm relying on private sales through the forum or ebay.
