After two years of waiting I will finally buy a projector as I always thought past offerings were either to expensive or not up to the level of performance I was looking for. I'm pretty sure with either of these two units I should be happy for years to come. Saw another thread z2 vs. hs20. However the price gap is much closer between the Sanyo z2 and the pannyL500. So by looking at the new specs of both the Z2 andL500 and also considering what the previous Z1/ L300 were like,which should be the better projector (keeping in mind this time around Sanyo has brought up the numbers on the resolution)? Who should have the better: 1)contrast 2) brightness 3)color uniformity 4)scaler 5)cleaner picture 6)connectivity 7)lamp life 8)mechanical issues 9)reliability 10)warranty.
