Anyone got any hands on experience with the Viewsonic VB50 "tuner"? It's a tuner/decoder that plugs into any VGA monitor & lets you plug in game consoles, watch TV, DVDs etc. It's not a plug-in card - it's purely for watching things using the monitor, no PC involved. I'm curious as to its RGB pass-thru quality, which is supposedly very good for its price ($99). But reviews are hard to come by.
