I'm making my first steps into LF.Bought a camera (cambo SC)for a good price. No w I have a dicision to make; should I buy used filmholders or new ones. If I loo k at second hand filmholders and for instance polaroid holders, most of the time they all look so very much used that I very much doubt they are working ok; I m ean its not possible to test them before I'll buy them. Could anyone have some t ips or tricks or method I can use before buying, to narrow the chance of getting unuseful stuff.
