The quality is about what I expected from VHS dupes. Some are better than others. I haven't ordered any SWs from him yet. Some examples of what I did get: The Concorde Affair was pretty rough, but Born to Fight and The Last Shark were about as good as you could expect. He seems to note in the descriptions when the print is better than average. These aren't restored in any fashion. You'll also have to tolerate burned-in subs on a lot of these.
I think his prices are about the best I've seen, is reliable and he's got a lot of Italian action movies which I've been after, so I feel like I've gotten my money's worth. Usually, I'll order two or three movies from an operation like this to get a feel for the quality and service they provide before dropping a few hundred dollars with them. I'll order again from him without worry.
All that being said, I prefer to order legit DVDs from places like xploited but a lot of this stuff isn't out yet in proper form.
