been reading up about the F71 in several forums. most of the discussions are about the issues of HDMI overscan and flickering colors. according to the UK and Australian forums the overscan issue has been fixed with the latest firmware upgrade.
i've also been reading about the new batch of x81 series that are now being sold in the US (as 42H, 43H, 61F, 65F & 66F series) and UK (as S8x, R8x, N8x & M8x series). according to early reviews the new models does not suffer from those 2 issues.
