Schneider's longer lenses are also excellent choices. I'd definitely look at used field cameras. I've been using 4x5 for over 10 years but just bought my first used camera last week. The camera had been used 3 times and had been in storage ever since. The bellows even had the new bellows smell like when it first comes out of the factory.
Used equipment is definitely the way to go.
You just have to keep watching until you find a good deal. Wistas and Picker just swapped the nameplates. I think Picker was a Wista dealer back then. Those cameras have short bellows and a lack of rear extensions, movements. Ron Wisner then built the Z6 for a while and later Picker had his own crew at Z6 building them.
