So my current (new) Amstrad PVR3 is keeping me up at night. The option I have been given is to take a Refurb Pace PVR3. Should I go for it because it is a refurb after all?

Also, regarding the phone line- I have been with Sky for many years and just changed to Sky+, so do I still need to keep the phoneline connected? Does this not create security issues e.g. if someone tries to buy something on my account etc?
