If it was my choice I'd go for the Super Graphic, it was Graflex's answer to the competition by European manufacturers like MPP & Linhof who were making cameras with all the features missing on Crown (& Speed) Graphics.

The Busch Pressman is roughly halfway between the Crown & the Super Graphic, depending on which model. I have aPressman & 3 Speed/Crown Graphics, if I saw a Super Graphic at that sort of price I'd buy it instantly
