My camera was a little too heavy (~15lbs) so I bought a new one (~9lbs)--a Canham 810 JMC. I ran a dozen sheets through it, and its great. It takes a little to adjust to the location of controls, but they are all pretty easy once you internalize their location. I also really appreciate that the camera is new, still being made, and supported by the manufacturer (Keith Canham).
I also accidentally exposed ~25 sheets of Foma 200 in 4x5. I had finished loading 6 sheets in a Grafmatic and flipped the light on--the rest of the foma was still in the dark plastic back but the end of the bag wasn't sealed. I developed a couple sheeds without putting them through a camera and one had significant fogging (probably the sheet on the top of the pile), but the other sheet had about 5mm of darkness on the edge. So I'll use the rest of the sheets for tests or unimportant things. But looking online, the cheapest way to get Foma 200 in 4x5 is a box of 25 FPP "Frankenstein" film. I don't usually go in for the odd repackaging but $1.20 per sheet vs. $1.92 per sheet (Arista EDU 200) or $1.80 (Foma 200) is worth the cheezy box.
