Mike: Thanks for all the information/links! It's really cleared some stuff up for me. One last question....I was looking at the Canon Rebel XS 10.1 MP DLSR camera, and I noticed a similar version (the XSi) ran about $200 more. The differences between them seem small, but is the XSi really worth $200 more if you're using it for just storm chasing?
Here's a link to the XS: http://www.amazon.com/Canon-10-1MP-...4?ie=UTF8&s=electronics&qid=1240004507&sr=8-4
A brief glance at specs show these differences...
3 inch LCD on the XSi 2.5 inch on the XS
12 mp XSI 10 mp XS
9 point AF XSi 7 point XS
3.5 frames per second XSi 3.0 XS
Doubt any of those are going to be terribly important but maybe worth extra $150(at least on Canon's prices).
I'd definitely recommend getting something with that live view as it can be really useful at times, like extremely precise manual focusing since you can zoom in 10x on the 3 inch LCD(so like focusing on a 30 inch wide image). Just useful at night or lower light...or other things like an annoyingly tight manual focus on a big telephoto.
