I purchased the Vizio over the Sanyo. The Sanyo actually looked a little better in the store but I felt the Vizio just needed some tweeking and I was right. Sanyo only sells it's TVs to WalMart and they have a bad rep. This is my assesment of the Vizio.
Nice design, the gloss finish looks sort of classy.
Impressive image in wide screen HD, can hold it's own against costlier units.
Good black rendering, not mind blowing but good
Good color rendering with lots of adjustment control
No audio output at all, What's up with that?
SD poor to good, really all over the map, not a surprise
Picked up 13 digital stations with basic cable
I am using a progressive scan DVD player through the componant imputs and it looks freaking great
Panoramic stretch mode is a joke
Cannot stretch image in HD,no Zoom control
No PIP, for me no big deal
Basically a stripped down budget WalMart TV, who could ask for more?
