Maybe your posting regarding your meeting today just sounded worse when I read it than things actually were.
As far as the shipping. Didn't this computer deal also include a CRT monitor...is he shipping that as well?
If he's shipping the computer & the monitor...is he really going to be making any money on this deal?...since I believe the last you mentioned you were buying it for $100.
It will probably cost around $25-$30 to ship the computer...and maybe at least that much for the monitor. This guys going to be lucky to clear $50 bucks on this deal!
If I have all the facts correct...maybe you should have just offered him $50 bucks when you met...and took it with you.
Of course I know that you want to be sure that it works...and even $50 bucks for a potentially non-working computer isn't worth it.
Good luck,
