Lost Camera

Well, I've misplaced my camera again. My kids keep doing cute things and I can't take pictures of them! I can't go on like this. It's been two weeks now and I can't find it. I've been wanting to buy a new one anyway. Any recommendations? I was thinking I'd upgrade to the $300/$400 range, but Costco's got the Canon Rebel models for $700/$800 ish. Maybe I'll do that?
