Yeah, you usually do get what you pay for. I went down the route of using less expensive film a couple of years back, and I ended up shooting two frames of everything, just to make sure one of the negs didn't have a bad pinhole in it or something. So I ended up using a lot more film, at the same or more cost.

Kodak, Fuji, Ilford = pretty trouble free operation. The peace of mind of knowing that my results will be as I expect is worth the extra money per roll for me. But at the time I really didn't have a choice either. It was all I could afford.

Either way, good luck with your test. I've tried Lucky film in the past (which I think the 100 and 400 is). Interesting antihalation properties, scratches easily in processing, but otherwise fine film. Have fun!
