I have been using Area 51 as a secondary provider for several months.

There are a wide selection of channels including all of the major UK and US sports channels. Most live channels are stable but a few have a missing file error, which I have only ever seen on catch up TV from other providers. They do not provide any catch up or on demand services.

Like most providers they provide an invoice a few days before renewal. Oddly even though the invoice provided functionality for payment using bitcoin, they claimed that my payment was sent to an incorrect bitcoin address and they have now suspended my account. The service is cheap $5 per month, so I have accepted the loss and and will look elsewhere.
