@EBone: Cool, I did GIS and cartography in university as well. However I only learned "new age" methodology, not with ink and mylar. Although it would be cool to find somewhere and pick up those skills for fun.
I have something close to that setup (40D and 70-200 f2.8L) and that thing is not light. you'll need to tighten your belt so much just to hold up your pants that it'll prevent you from having kids.
I gotta give it to Canon on this one. I think it edges out due to higher MP count. Although to those interested in buying their first SLR, I highly encourage going up to the 50D. It's a much better body and it will last you a much longer time. The Rebel series cameras will feel like a toy after you handle a 50D and above.
