Yep, a bright line finder may run you the price of three or four FED 2's, but you will get some use out it on other cameras. My favorite use is with an old Agfa Record III shown here bringing up the rear. It's a great combination, as the 50mm frame lines are a bit tighter than the 105mm viewing field of a 6x9 medium format folder.
