I bought 3 Fidelity Deluxe film holders used from keh.com, i am not sure if they are working fine from this thread, but i need to start to shoot LF to find out, but i am really looking to buy new film holder just to be sure i have something new at least, i was going to buy TOYO film holders as long they are available with Fidelity just to see the difference, but i really look for to buy a Polaroid back just in case if possible/available.
