Pete, just borrow one from a dealer, like I did, and neglect to take it back. Yes, I did pay for it, and yes, I did call my buddy at the store to let him know that I'm on to his sneaky sales practices!! He told my to drop by the next time I'm in town, and he'll loan me a 200-500 f/5.6. I think he's got me pegged...
