As someone who has 4 Graflex's I'd be careful in your choice, because there are quite serious limitations with the most common models.
I use my Pacemaker Crown Graphic and an emasculated (no shutter) Pacemaker Speed Graphic for hand held work, but their very limited range of movements is very restricting for tripod work. There's some rise/fall and tilt in landscape mode, but no movements at all in portrait mode. The upside is they are cheap.
However the less common Super Graphic's are quite different and have far better movements as well as a revolving back. This is why I've recently switched to using one instead of having to make a choice of either taking my Wista or Crown Graohic (or both) when off shooting for a few day's.
