I've been using the $10 package for a couple days now and everything seems to be working fine. I don't use proxies as much as some of the people on BHW (to say the least) but it is certainly nice to have proxies ready when I need to do something. Peronally, I am tired of the free lists! I hate being in the middle of a job/project and have them crap out on me. So far, this hasn't happened with this service.
I try not to spend money if I don't have to but I am starting to find that it is worth the money to make small investments like this. I think you will find unhappy customers with any business, no matter how good it is. For me though, I don't have any complaints yet. Hope that helps!
