I think it's good to be price conscious, but at least in the US, Acros has been pretty affordable,and Kodak's 120 stuff has recently come down in cost by about 15%. I'm not interested in buying mediocre quality film to save a dollar when it could ruin the results of a once-in-a-lifetime photo. A false economy compared to the gas, camera equipment, etc.. Foma used to be a cheap film, but it's not cheaper now, and it's not as good as kodak/fuji/ilford in terms of quality.
