I dont know which exhibition you where attending but both were at the last one I did, I think, I have no reason to knock them. I would ask if you directed the right questions to them and hope they provided you with the correct answers. what I would say is do your research and know what you want before you commit. good luck to you wherever you buy.

I agree with Bryn.. take your time...do a lot of research and a lot of legwork....also forums like this help
