In spite of the whole T2 Garand thing, I've bought a few guns from John personally through Marstar and never been disappointed in the gun - he's not the easiest guy to deal with and doesn't tend to answer emails in a timely manner, but when the guns arrived I had nothing to complain about. I know a lot of people will tell you not to deal with him but I figure that's a decision you should make for yourself.
If you really want a collectible Brno M95 I'd say go for it. In fact I might be tempted myself if I hadn't spent too much gun money in the last few months. That said, if you just want a representative / shooter M95 you could probably find a Steyr or Budapest for half that price without too much looking. I picked one up a Bulgarian refurb Budapest true carbine for $200 out the door at last year's Brandon gun show and had a choice of a few.
