I currently use the TP-LINK N600. It's an older router (probably better ones on the market now) but it still goes strong. Dual band wifi and 2 USB ports. Also used with sky broadband ADSL service. It has good customization, QoS etc... And googling shows it going for as cheap as £15. I don't believe it's capable of VDSL though. Just in case you want a bit of future proofing.
You would also need to get your SKY username and password. I found it extremely difficult getting that information from them so resorted to other means. Which i'm unsure i can speak of here.
