In the couple of weeks I've been using blackVPN, it has proven to be a reliable solution to watch US TV Shows through Netflix, Hulu or ABC Player on my iPad. I'm based in Europe and normally I can't use these apps, but blackVPN gives me access.
Speed is fine for watching TV Shows. Haven't tried using it for anything else. Connection is almost always established immediately and I have yet to see a disconnect happen. At first I didn't receive the automated e-mail with my username and password. After sending a mail to their support, blackVPN answered within two hours with my username and password. As far as I know, blackVPN is the cheapest provider of these kind of services with these quality standards.
