I am on the lookout for a 37 inch model to be used prob 50:50 for TV and DVD vieiwing. I have seen the Sharp models in John Lewis and the lack of screen surround is a big plus point compared to some other manufacturers. I have also been impressed with the picture quality of the 37GD1E. However - does anyone know why the GD range is consistently over £1000 more than the GA range?? I know it has a digitial tuner - but is there anything else on the panel to warrant such a big price differential?
