Get on eBay!! I just got an A620 for $245 with overnight shipping ($225 without overnight shipping). You've just got to be patient, though. I think it took me a week or two to wait for some auctions to end. The one I almost won had the CF wifi adapter (ended up selling for $217 + shipping), which you could probably sell for $40 and then put that towards the CF memory or keep for the wifi.
Anyways, I've checked EVERY electronics website, and although you wouldn't have to go through the hassle of bidding, they couldn't match eBay. Of course for the most part on eBay are the "Buy it Now" auctions...for more than those websites, but if you're patient one will come along that you can win for under $250 (
