Well, I learned 2 things recently.
1- cameraquest's MPs are all sold out.
2- KEH's auto-quote lists their buy-price of a mint leicavit at $475.
I am not planning on buying for another 2 - 3 weeks, but when I do it looks my decision is pretty much made up. MP from adorama and I'll try to sell the leicavit once I get it. Actually, since I am happy to get $475 for the leicavit I may try posting it here first to see if anyone is interested.
FYI on my inquiry to cameraquest. I am not as impressed with his customer service as some of the other people here. I wrote to ask about the differences between his warrantee and leica's and got a 1 line non-answer. This is pretty in-line with my previous experience; after purchasing a camera, lens and accessories from him last year I emailed him a question about it and never got a response.
I'm glad other people have had more positive experiences, but I'm not all that into him.
