I've also gotten back into large format, and I own a Super Graphic, a Tower Press (Sears-badged Busch Pressman Model D), and a Cambo 45SC monorail. All have their assets and drawbacks. The press cameras are lighter, but with that comes less flexibility in camera movements. The press cameras "normal" lens is usually around 135mm, slightly wide from "normal" (150mm). From there you can add a long lens and wide angle. The older press lenses were coated, but not to the extent of the modern Japanese and German lenses.
The monorails have nearly infinite lens and back adjustments, and you can really exercise artistic control.
There's also the field camera, metal or wood, which allows more movement than the press cameras, but less than the monorails.
I also own a Graflok 6x7 back, and I use a Cambo 6x7 back that loads like a film holder, but allows for 6x7 images on 120 film.
A newer monorail will probably have good bellows, but the older Graphics and many older monorails may have pinholes in the bellows. The other consideration are the film holders. They, too, can develop leaks over time.
There are fewer technicians to CLA the older lenses and shutters, and you also have to be aware that these older lenses may have coating, fungus, and cloudiness issues, all unrepairable for the most part.
The other thing is a sturdy tripod. A tripod for a DX digital and short zoom, will not support a Cambo monorail with a 210mm f/5.6 when its windy. Good used tripods can be found, and a Bogen 3036 and heavy 3047 head can be found on places like
eBay.
To load/unload film holders, you need a changing bag, or darkroom. You'll also want a loupe to magnify the ground glass image while focusing/setting apertures. A focusing cloth is also advisable, especially on a bright day.
Right now, there are a number of labs which still do E6 transparency processing (mostly mail order), and some local labs will still do C41 color and B&W negatives. That leaves printing or scanning. I scan all mine and edit them before printing.
The results can be stunning, and the sheer size of the files can be a load on your hard drive. The grain is debatable, since there's a body of photographers which use the film grain to their advantages.
There are other considerations, and if you search the web, you can find a few forums which specialize in large format photography. There are also a number of hard copy books which are extremely informative.
