Last week Sky phoned me to try to get me back as I had cancelled my subscription.
This was the third time they had called over a period of 4/5 weeks.
This was third time lucky as they gave me their best offer, a FREE SKYPLUS BOX with 160Gb hard drive, albeit reconditioned but with a guarantee and best of all for NOTHING.
Also on offer was sky's full package at �10.00/month for 3 months. I generally take an offer but always cancel one month before the end, go onto the freeview channels after the final month and wait for the call from the Sky REINSTATEMENTS DEPARTMENT.
As far as I am aware you can put a quad LNB onto your original dish but you will have to run another good quality, ie SAT 100, coaxial cable as a skyplus box requires two feeds from the LNB.
