RT - A 2.1MP camera is fine. Actually, the CCD's on the 2.1's are much better then the 3's.

I'd suggest the following upgrades:

A Pelican case. It will keep the camera dry, and protected.

2-3 set's of 1700 mAH NiMH batteries. Trust me on this one. Just remember that a slow recharger will supposedly give you longer bettery life. Fast chargers supposedly shorten that life. How much so, I wouldn't know. Here's a good site for batteries:

AT *LEAST* a 100MB Compact Flash Card. Personally, I'd get a 256MB card, if you camera can support it. $100 will easily get a 256MB card. Go to pricewatch.com and search out a card or two.
