I got mine from dfs - thought I would buy cheap cos a lot of these dear ones look very uncomfortable - the price included sorting it if it goes wrong or breaks, also am paying it up cos it is interest free and I thought it would be a good 'lever' in case a repair was needed; however the mechanism did go wrong after a year a few months ago and there was no problem - phoned the shop and they arranged the appointment, the repairman phoned the night before to confirm he was coming then half an hour before he arrived and fixed it there and then. So in this instance cheap is good... and in a few years I can buy another pair if I want to cos it is so cheap lol...
