Regarding "The Doctor"'s post, before you buy from a company you never dealt with before (either online or offline) check out
http://www.resellerratings.com to see if there have been complaints about that company. Also, before buying online or from certain areas in New York, check out this article:

As for buying an older camera, I'm all for it (up to a point). Personally I bought an Oly C-700 when the current model was the 720 and the 730 was going to be announced in a month (but I didn't know about it)...I saved $200 on my purchase because the store wanted to get rid of the older camera. I said "up to a point" because some older digicams were very basic and didn't have any features (like not being able to view the pictures you've taken). Check out Steve's Reviews before buying as well.
Also, if you live in a big city you may have a (trustworthy) camera outlet store that deals specifically with older models...living in Toronto, I have the Henry's Outlet Store to go to:
