Jason -
Glad you like the pics. For everyone else, Jason's cars look even better in person then they do on the screen!
Just for comparison in your shopping, my digital camera is a 2.2mp Kodak (model DX3500) and if I remember correctly was under $150. For still photo's and close-ups it is great. Action shots and zoom leave a lot to be desired.
For high quality photo's with lots of action (ie., the track shots I sent you) I still use my 35mm camera with zoom and then scan them in on my $20 scanner.
As a selling point to the wife, just remind her that she'll be able to use it too
