I'm quite happy with my 3.3 megapixel vivitar for now. I do hope to got to a 5 mega pixel sometime soon.

Actually, the price of five megapixel cameras have become really cheap lately. You can often get the Canon PowerShot A95, the Casio EXILIM EX-Z50, and the Konica Minolta DiMAGE X50 for well under US$400 at online retailers.
I'd say you're livin' in Heaven. Great photos. Stole a couple.
Some nice pics!
