I am also thinking of buying from digital direct. A friend of mine told me he ordered from them one day and it was delivered first thing the next morning as a driver for Amtrax lived across from him. I havent bought from them yet but if they stock the TV I want (when i eventually decide) I will go to them as the prices seem good and they use a reputable delivery company. If you decide to go with them, let us know what the experience was like.
A click on the homecinematv website will tell you that they are part of Hughes Electrical Ltd. This site undercuts the Hughes Electrical website by quite a substantial amount in some cases! Are they in competition with themselves ? I can vouch for this company as they run a chain of well established stores in East Anglia. First class service.
