I bought from him about a year ago, and while it was a bit of a hassle cause I needed to bank wire him the funds, otherwise, everything went flawlessly, all the equipment was delivered as promised and in working order.
One other thing I'd mention, he does not seem to update his webpage, almost never.. It looks almost like it did a year ago... When I sent him my order, he replied that everything I'd requested was sold out, and asked if I would like him to let me know when he gets it in, to which I replied yes. The next day, he stated he had about 2/3rds of the things I wanted, and asked if I still wanted them. I did, and all went well from there.. :)
Personally, I suspect he doesn't have nearly the stock he shows on the webpage, and once he gets an order just goes on a shopping hunt.. :) But he doesn't act like he has things he doesn't, and he delivers on what he can get, so I'd say go with it. :)
