So, I just sold my XTi and grip to a friend of mine, now I need to order a 40d, but have a few questions. I sold my friend the body and kit lens, so now the shortest lens I have is my 50mm 1.8 and my 70-200. Now I didn't usually use my kit lens much, as 90% of the stuff I do is with my 70-200, but I've seen people talking of buying the 40d with kit lens and flipping it for money due to the rebate now. I even heard someone say that it was dumb not to buy the 40d kit and sell the kit lens for a few hundred. What's the deal with this, is that really the way to go?
