$200 is a good price for a Crown Graphic and half decent lens, a 135mm Xenar is OK at f22 but edge sharpness is poor wider open. any more is over the top.

For some reason people are paying way over the odds for Speed & Crown Graphics, while I have 3 they aren't the most versatile of 5x4 cameras but they are excellent for hand held work where movements are les practicl anyway.
