There is also this company that give you a UK IP address so you can watch Sky and BBC iplayer etc. A quick google looking for complaints show on the whole they are OK.

They use the same system as Iberbanda and Eurona.

Iberbanda have a deal that gives you 3mbs download speed free Spanish calls and 150 mins to Spanish mobiles for 47 Euro a month (IVA included)

If you need your BBC and ITV after the Feb switch-over it maybe worth going with one of these companies until the cost of the bigger required dish comes down in price.
