Definitely get the biggest you can afford, when the changeover to all digital is finally done you will appreciate the extra inches and can sit closer as well. I got a 60" Sony RPTV and it now seems normal, not that impressive anymore, I don't think it matters how big you buy, you will get used to it. I only sit about 8 feet away from it and it looks great, onHD sources of course. Standard def sucks, so I watch standard def on my old 32" Toshiba.
