For those that want a free service and don't mind ads, there's also http://hotspotshield.com and http://expatshield.com which will let you access US and UK services respectively.

The UK one doesn't support OSX, so I run them both from within a separate Windows VM if there's some restricted service I want to access. That way their VPN software doesn't get in the way of my other activities, and I only get ads injected within the VM.
