Virgin Media cable broadband is not available in my area

Hi,
I live in Evasham and I’v signed up with Sky package six months ago but I want to move to another provider as Sky packages seem a bit expensive. I’ve found that my choices are limited as I can choose my new package among AOL, Tiscali, TalkTalk and Orange internet service providers.
Both TalkTalk and Orange packages appeal to me as I can go for free broadband when I sign up to their call plans but I can’t decide between these two providers.
Virgin Media cable network is not available in my area so which ADSL provider offers the best packages in my area? Can anyone has suggestions for me?
Thanks in advance
