The only reason not to roll your own VPN on some private server, is the lack of deniability. The dedicated IP of the server is tied directly to your name/credit card. A public VPN, while also tied to your banking info, usually acts as a NAT. Multiple clients exit the VPN given the same source IP address. If no logs are kept (as promised on most services), no one can (accurately) tie an IP address to your name. I personally use the BTGuard VPN for this reason.
