I really like blackVPN! It is the first VPN-Provider I use due to some network restrictions at the student hostel.
The speed is okay as I think, I use the UK-Server. It could be a quick faster. With DSL 6000 I got a download speed of ~ 530kb.
The support is friendly and fast. I had some connection problems at the beginning and they helped me almost immediately. I really appreciate that.
The price is cheap and all in all blackVPN has a good price-performance ratio!
