Right now have a 20 inch Panasonic flat TV (20SL13) and thinking of upgrading. I be sitting 6 feet from TV screen. I am thinking that 6 feet distance might be too close for a 32 inch TV. So I was wondering if anybody sitting that close to a 32 inch-or bigger and their eyes are not bothered?

My options are (from Sears):
Panasonic 27SL14 $329 (27 inch..flat)
Toshiba 27A34 $229 (27 inch..non flat)
Toshiba 32A34 $329 (32 inch..non flat)

Which one would you go for
