Have you shot w/ your M2, Gene? I read you are looking for a Summicron, but you have other lenses, right?
Dave, I really feel for your state of limbo, hope it's only a post-Rita delay. Here's my situation (Gene, read no further, lest I make you feel guilty): I find what I think is a great deal on an M2 w/ a recent CLA and in "mint-" condition. I e-mail and talk to the seller, ask lots of questions, and he keeps saying, "mint-, mint-, mint-." I quickly sell my "very good user" M2 to Gene and remit payment for the new M2. So Gene's M2 arrives yesterday and he seems quite happy (Gene, I hope I'm right). My new M2 arrives yesterday, too, and guess what? It has more dings than the one I sent Gene! I thought I was such a smart guy, and now I have no M2, since I returned it this morning and asked the seller for a refund. So Dave, at least you have something to look forward to with the arrival of your M6. I'm now waiting for a refund check before I make any more smart moves.
