Opinion on GOOD digicam

I do a lot of projects, and prefer to have a lot of documentation as far as testing & failure along with unpredicted results goes. Part of this, besides jotting down notes, etc. is the need for quick, and fast high-quality photograph pictures.

Could somebody, from their expierence, recommend a good digital camera for me to buy that takes film/conventional camera quality photographs at least a quality, where the picture's demensions are 800x600 on my desktop and it's flawless(or nearly) quality? Good quality at higher resolutions is always welcome. Moral: Good quality.

Any suggestions? Model, brand, etc.?
