I had a lot of problems with the website last week when ordering my RB67. It got sent to my address instead of my girlfriends(she's giving it to me for christmas). My order appeared after the 2nd time checking out, but showed up as "on hold". One 2 minute call to KEH got it shipped. While I didn't like the website problems, I can't argue with the quality of the product and shipping speed. The lens had flawless glass and the back was new except for a few light scratches.
The exact same issue happened to my order with the 150mm S lens.
They are doing their best to try to work through the issues, but I don't envy their sales people right now.
