blackVPN is the first VPN provider I've tried, and so far my experiences are very good. So far it happened twice that I didn't get a nameserver assigned on US while it worked fine on UK. 15 minutes later after a reconnect everything was back to normal. I don't encounter any lags or buffering, speed feels just like without VPN, not sluggish at all. And the price feels reasonable.
Now I am a happy viewer, no more "not available in your country"!
