Alright guys and gals I was going to buy panda film when I noticed diamond foil. The difference that I first see is one is $9.00 and the other is $90.00. Anyway I was wondering if the diamond foil could really be that much better. If so is it necessary? Or would it benefit me a great deal? I'll spend the money if it would make that much of a difference but if not I'd rather save some $$$. Input?
