I just saw the wood/brass Wista in a shop in London, absolutely beautiful camera.

I'm something of an armchair 4x5 shooter, i.e. I don't shoot large format at the moment, but I like to read about it. I find a lot of the Youtube videos helpful, and also, I'd get a cheap loupe to make sure you're in focus. I use one on a 6x9 camera with ground glass, and it's pretty helpful.
