For a few small parts and tests, inexpensive film, bleeder, peel-ply, etc would be OK, although they may not work as well, but if you graduate to bigger, more complex parts, you will have enough money in fabric, core and resin, and more than enough of your time in getting it all ready, that you will not want to take chances with anything but the best in film, seal tape, vac pump, etc. A failure of almost any part of the system means you have lost your investment of time and money in the part. I don't want to chance it. Just my opinion after infusing some big, complicated parts.
