im a pv8 user myself and it is a good buy
, side by side comparison might not be as fruitfull since these units have basically the exact specs
, the only differences have already been stated above (3 hdmi, piano finish, swivel, sd card slot)
my take on this is think about what gadgets will you be using on the tv, will you be using just 1 hdmi device? 2? or 3?
but, if it was me, id go for the pv80, an additional hdmi slot is what ill go for specially since i have multiple hdmi devices =)
