I recently felt as though I have stepped out of the "intermediate" level of photography and am now in the lower end of the "experienced" photographer. With this step, I believe that it is time for an upgrade. I bought the 400D back in August of 08. Don't get me wrong, I LOVE my XTi, but reading a few different threads yesterday made me realize how much it's holding me back. I thought that I had settled on the 40D. I looked around on Craigslist hoping someone was looking to get rid of theirs, and I found one not too far away with the EF 28-135 IS USM for just under $1000. BUT I did some further research and started leaning more towards the 50D. Now my question is, which is better bang for buck? The 40D with the additional lens, or the 50D body (possibly a kit)? I know it sounds like a no-brainer, but I figured I'd ask the professionals first.
