I'll probably try to sell them locally.. the last time I sold something on OT I got raped by Paypal fees and shipping, but I wanted to gauge interest I got the 10-22 in February.. only used it a few times then lost my job and haven't touched it since. I've had the 50 a few years, but it's in great shape. It's had the UV filter on it since day one. I bought each one new and I've been their only owner. The 50 is missing UPC cause I sent it in for a rebate back when I bought it, but I can verify that it's in great working order. I sold a lens on OT about a year ago, and I think that guy (QUICKsomething?) would verify a smooth transaction.
