It's actually a short story, but I suck at typing so it would take forever to get it out. What I've got isthe now discontinued70-200mm 2.8LIS USM that just came back from factory (still sealed up) that had it's IS replaced under warranty. I bought it newnear the end of last year and have all the goodies that came with it. The hood has about twenty little shiny marks on it about 1/4" long. Other than that, it's all great. I know what I'll be selling the 17-55mm forand know roughly whatthe Tamron 28-75 2.8 will be going for, but the 70-200mm I'm not real sure. "L" hold there value so long as there is a market, but how well? I'd like to sellthese by the end of the year. Any thoughts would be welcome.
