Shopping for a digital camera

My old digital camera was sold on eBay this morning (for $62 - yippee). So it's time to get around to buyer a new one. I'm going to play with cameras at Best Buy and Ritz Cameras tonight. Unfortunately, the ones I really one are from Sony and Olympus - neither of which use regular SD cards. Ugh! Since we don't want to deal with two sets of cards, I have to get one that uses the kind our other cameras have used. 

Any suggestions? I want something tiny, but with as much zoom as possible. I don't think I'd be able to stand anything less than 5x. I figure I'll play with them in the store, then shop online for the best price. And I'll pick up a high capacity HD while I'm at it.
