Having recently purchased a widescreen televisio, I have decided to take the leap into digital television with ITV Digital as I don't have cable and wife's not keen on dish! I presume that prepaid subscription is the best option. If so, where is the best place to purchase this? Do all the outlets have pretty much the same deal? Also, is one make or model of digibox superior in performance to any other? Are there any other issues I should consider? Thanks in advance.
