From what I have heard the larger sized sets are not reliable despite the name of the manufacturer. 50's are prone to faults and it follows that 60's might well be worse. I have stuck with a 42 and its the second one now, the first lasted for 8 years, this one has been going for 3, Panasonic plasma.
As for Sky, I have just thrown them out (that was a hell of a fight to have them accept it) for consistently 'iss poor Customer Service and now we only have Freeview and FreeSat, coupled to a 500Gb 4 channel TiVo which gives us the same as Sky+ but for free. There are many HD transmissions on Freeview and FreeSat and they are increasing all of the time. Incidently FreeSat also uses the same satellite as Sky and so you do not have to move the dish. I did my Sky boxes, 4 of them, in just under an hour.
It is also possible for a Sky set top box to be retuned to pick up the FreeSat programs and you do not need a card to do so, just a list of the frequencies and the knowhow to retune the Sky box. As both are free why spend what you do not need to and raise the profits of Sky for a poor customer service and the inevitable repeat after repeat after repeat after repeat on all of its channels which they tie you into a contract with? At the end of that contract they then also demand a 31 day notice period to end the contract which have to formally apply for. If you, like I did, paid so the account was well into credit and that the credit far supassed the amount owed at the termination you then have to apply again and wait a minimum of 31 days again before they will even consider a refund. No joke

, I have their written proof of that and I have now registered a claim against them.
Sky also charges you as part of its 'entertainment' package for the programs you get for FREE on Freeview and FreeSat.
Think before you spend....
