I can't see that web page from where I am, but I guess if they're sold out I don't need to.
With Setanta gone down the tubes I imagine that there will be other similar offers.
Yes, indeed.
A friend recently spotted a Setanta box in a supermarket (Asda/tesco, or something I don't know which). It was closer to £15 than £4.99, and I know you can already buy freeview STBs for that kind of price, but he reckoned it was heaps better quality than the usual cheapies.
