The audioquest stuff works good for cleaning really dirty connections, but I think it is more than 10 bones. The xlo wipes are the ones that I have found to make the most audible difference, and the progold seems to be not quite as good. The audioquest, I find, doesn't sound as good as either. I haven't tried the sumiko contact but I am curios.
I would not be without contact cleaner. The difference a clean vs. dirty connection is important for sound quality.
