It depends on who you speak to.... Lee is the owner, very knowledgable. Another staff member specialises in radios. I did have a problem once buying a T-ring for my D70, trying to explain to the woman on the phone that it was a Nikon SLR, and the mount hadn't changed for eons.... was sorted out in seconds with the boss though.
I tend to shop pre-informed anyway, so it doesn't bother me too much....
