When it comes to cheap large format cameras, you are really talking about one of three main choices: press camera, monorail, or old wooden field camera such as the Agfa/Ansco or B&J models we have been refering to lately. As it happens, I have never owned a press camera, have used them only once or twice, and have nothing useful to add about them. I just don't know them.
The Agfa/Ansco and Burke & James wooden tailboard cameras are very usable. As Nick and rootberry have said, they are simple cameras but old: most have faults of one sort or another but because they are simple and rugged, most can be easily fixed. They are bulky to use in the field and heavy but cheap. That's the trade-off. More modern cameras such as the Wisner (which I've had,) Tachihara, Shen Hao, etc. are all lighter and fold up much smaller, making them somewhat easier to stick in a backpack and carry off over miles of trails. They also cost more, are more fragile, better with short focal length lenses (less than about 125mm,) and prettier. It is not an easy choice but if I had the choice I would probably buy a newer camera simply because I'm a photographer, not a camera repairman. I have not always had a choice, however, and for someone with severely limited funds, one of the old Ansco or B&J tailboards is an excellent buy.
I have also used a monorail in the field: a Calumet CC-400, to be exact. Very bulky, doesn't fold up well at all, and the 4x5 model is at least as heavy as my 5x7 B&J. It has it's quirks: it is more rigid but the focusing mechanism doesn't work as well. The rotating 4x5 back is more convenient than the way most field cameras want you to remove the back, rotate it, and re-attach it. Geared front rise is very nice. But overall, it's my last choice for carrying around. I'll take the B&J before the Calumet.
Oh, and before I forget: Graflex made some unusual film holders (4x5 film magazine, reducing backs for 6x7, etc.) which were too "fat" to fit under the usual spring back, so they also introduced a back where the ground glass assembly can be removed from the camera back, and one of their Graflex film holders attached in its place. That's a Graflok back. A Graflok back also works as a regular ground glass back, so if you do have a camera with a Graflok back you aren't losing anything. You might want a Graflok back if you are interested in using roll-film backs on your view camera, otherwise you don't care. Most current film backs (Kodak and Fuji readyloads, regular film holders, etc.) work with either a standard spring-mounted camera back or a Graflok back.
