G'ah!
Use caution when buying film on
Ebay. I'd avoid overseas shippers at all costs. Often you will find that your film has been xrayed once or twice by the time you get it. This is not an admonition of any overseas vendors, but rather of our customs folks.
I bought $50 worth of film from an overseas vendor last year, and every last bit of it was garbage by the time I got it.
I'll second the suggestion of Arista films from Freestyle.
I'm looking at my Freestyle catalog right now, and Arista film is listing for as low as $1.49 for 35mm and $1.29 for 120 Size
Arista is what I buy for large format, too. 25 sheets of 8x10 film for less than $35 when everyone else is over $70 for the same thing. Quality is very goo, too. It does have a lower silver content some other films, but it is marketed to students and educational programs, so they keep their prices pretty low to appeal to those segments.
For comparison in the same catalog, Ilford 35mm Delta Pro 100 is $295 per roll and the 120 Delta 100 is $2.89 and I would rate these films as equals.
