While I'm not as enamored of my V8, my 5x7 is one of the best cameras I own (Out of 56+. Yes, I have a problem.). Compared to its American contemporaries, it is far and away the cream of the crop. It's light, rugged, solid, beautiful, etc. It's just a pleasure to use. My only non-American LF of similar age is a German reisskamera, which although truly a gem with it's beauftiful wood, almost incredibly fine joints, etc. , is not nearly as versatile.
My 8x10 is in better shape than the 5x7, but doesn't seem nearly as rigid as the 5x7, and weighs as much as my 8x10 Korona.
I got both my Deardorffs for less than the price of a single, used Canham. If I had the cash, I'd have a Canham 5x7 and a Phillips 8x10.
I've never had the pleasure of seeing a Gandolfi up close. Or one of those beautiful Japanese cameras from the 1920's-1950's.
