Am I an idiot, deal shopper or just a gear whore? Just picked up the newer canon 70-300 IS USM from a local guy for $195 I know they go for about twice that on ebay and about triple if new, but I just thouhgt the deal was too good to pass up. I already have the older version of the 75-300 IS and the 70-200 IS MKII with the 2X Tele, but sometimes just like to go out and shoot without changing lenses, converters, caps, hoods etc. I figure I can get about $150 out of my old lens and hood, so the whloe thing will only really cost me about 50 bucks and could actually make a bit of money if I needed to sell the new one. Anyhow, help me justify my actions.
