I have never bought anything from these guys and probably never will even though they seem to have a lost of NOS of Nikon lenses (online) that have been removed from the catalogue such as the 180mm. (suspicious!)
The reason I will not ever buy from them goes back to when my (then) girlfriend was shopping for her micro 4/3 Olympus. Of course they had it in stock and of course they had it for a good price. But the catch was that YOU COULD NOT DEMO THE CAMERA! They couldn't even turn it on for you. All you could do was hold it and PRETEND to shoot with it. Now, this was a $1,000+ purchase (with lens). Furthermore, this is not some throwaway in a year compact. This is a system you are buying into. You really need to be sure that the camera will work for you. You have to kick the tires. People do not buy cars without a test drive, right?
I think the reason for it had something to do with not being an authorized dealer which only only raised more red flags. Between the NOS, the two stores in the same location and the too-good-to-be-prices, I will only suggest you stay away. Also, the staff are just sales people--they do not strike me as being photographers or experts in this hobby/profession at all.
