i just picked up a 350d body and I need a lens for it. Should I pick up a kit lens off ebay? (They're going for like $50 shipped) or something different? I plan on shooting a good mix of general point and click shots (people, scenery, whatever) and it will see a good amount of car shows, track events, etc. Should I go with the 18-55 and a 75-200? I'm traying to stay as cheap as possible, since the camera was a total impulse buy last night. Anyone have a kit lens they feel like donating to a SLR noob?
