Hey guys, I've got several questions, again. 1. Canon or Nikon? 2. Which lens are the most compatible with cameras, or does it really matter? 3. What about the durability of the lens and camera? From my understanding most seem to suggest the nikon d80 ( the camera seems to be in mid-range) I'm on a budget, nothing over $1200. 4. What would you all suggest for a canon that's in mid range on price, is the canon eos xti a pretty good camera, and which one is the most recent of of the xti that's in the mid-range price? 5. Would you all recommend purchasing equipment on ebay, providing the seller has a very good rating 100% score? 6. Which lens are recommended for portraits, outside shots, & close ups? Thanks for all your answers!
