I have done quite a bit of research and given my budget, have whittled down my options to the following 3 packages. I would mostly be bringing my gear with me when I am on travel and would take a mix of landscapes, buildings, people with landmarks behind them, etc. (just about anything) I am not sure how important the 18-28mm range is. I know that wide angle is good for landscape photography but how bad is a 28mm? Also, I am not sure when 135mm would not be sufficient and one would need to go all the way up to 200mm. Last but not least, I am not sure how convenient/inconvenient it would be to change lenses while on travel. I understand that the D60 and 40D are very different cameras but I am willing to look at both of them. My options are as below, would be most grateful if people on this forum would be able to help me out. Thanks in advance!
1. Nikon D60 with 18-55mm VR and 55-200mm VR ~$850
2. Canon EOS 40D with 28-135mm IS ~$1150
3. Nikon D60 with 18-200mm VR ~$1300
