Hitachi's web site shows info on the 51S715 and 51S710 there is no info on the S510, or was it the S500. Is one better than the other? I read on the Home Centric forum that they changed the crt's. The good ones they had in the 2003 models are only available in the directors series, and they went with cheaper ones on others to keep the price down. Any thoughts on this? Was that the swx/twx/xwx series? What would we lose out on with the 2003 series? What model year is 51F500? Thanks again, George Does anyone know where they sell Hitachi's and have knowledge of them? I guess we're looking for a chain store. We live in Michigan. Haven't had any luck at Sears or Circuit City, maybe haven't run into the right person.
