I would wager that for every person who says they have had better results from homemade and cheaper products than mesosilver you would find 100 who say just the opposite. I have very, very seldom seen people contend that they have better results with products other than Advanced Colloidal Silver and Mesosilver (the two top rated true colloidal silver products), whereas I have seen scores and scores say that one of the two top products gave them the best results.
I realize that it is hard to wade through all the marketing hype and so-called silver experts - especially with so many of the products claiming some kind of unique superiority. Interestingly, Advanced Colloidal Silver makes no such claims anywhere on their site or in their literature. They have let their product stand on its own merits and results.
As I think I noted earlier, homemade mostly ionic silver should do you just fine for most purposes and the Silver Puppy is one of the better units out there in its price range. For the best of both worlds, get yourself some top quality commercial product for extreme situations and make your own solution for pennies for general use.
