I agree with wheelo, ufortunately its one of them pay your money and take your chances as far as cable goes at present bucka. everyone has different circumstances. And no one can tell you if they will last another week or another year. My personal opinion is that we have seen the best of cable, and their days are numbered, but that is not an informed decision. But then it depends on how much the possibility of loosing £140 or so for a Kryptview effects you if the worse comes to the worse, if you can just put it down to experience and not cry about the money, then as you say, it is the easier option and may be worth a gamble. I certainly would not consider a Starview, not at present anyway.
I am not too clued up on the Sat side of things as yet, but if you are prepared to do the research and learn the ins and outs, then it may be the better option, again everyone is different. If I was starting afresh (I have a Kryptview) I may well be tempted to go Sat way after recent issues with both Kryptview and Starview. I do not feel qualified to comment on which sat box is the best, but there are plenty of threads on this site to help you decide (both cable and sat), and you and I will get all the help we need here should we go down that road.
