I was gonna sign up to that service 2 things put me off..
1 - you have to buy a router from them, its a DG834GT for £80 which is quite a bit more than you have to pay if you look around, I already own this router and didnt want the hassle of getting another and selling it at a loss on ebay
2- 12 month contract. This contract isnt like a regular one that most ISPS offer where if you cancel part way through you pay a fine of like £50, with ukonline you have to pay the full 12 months.
