I must admit that the high price of the 100 count box kept me from trying Azo for some time. While I did want to try it, it was a large investment for something that could have turned out to being not to my liking. It wasn't until I got some old 4x5 sheets and a 25 pack of 8x10 on e bay for a few bucks that I saw how good it was. If that hadn't happened I would probably still be holding out and making due to graded enlarging paper for contacts. Its just like anything someone tries to sell...if you know its the best, then give them a sample and rest assured that they will come back for more.
