Instead of the cameras you listed, some of the best values around are used Zone VIs and Wisners. Save the cash for a good lens and please don't overlook Schneider. They are the only lens manufacturer that has a full service office in the US and their service for both LF and enlarging lenses has been outstanding for me and collegues. Nikon's LF line and service have fallen off the face of the planet. Sch, Rod, and Fujinon.
Wood ages nicer than metal, both in cameras and tripods.
Like William mentioned, every Wista I have seen had a short bellows. Got a cheap 5x7 Plaubel monorail to start out with, but it's a pain aoutdoors. However, my Toyo seems sturdy and rugged enough for rough aoutdoor conditions. I talked to suggested that too light a camera with long bellows extension may give you trouble in windy conditons, which you always encounter in mountains and seaside areas. With that the limitations of the Toyo are somewhat negligible.
