Hi I'm going to order a PJ this week (finally time to take the plunge). I've demoed quite a few and the HS20 was the best of the LCD's, although the Hitachi PJ-TX10 was fantastic value for money. I see rainbows so DLP is a non-starter. However I cannot demo a Z2 anywhere. Can people who has seen/demoed/reviewed both the Z2 and HS20 give me an informed comparison. The Z2 is quite a bit cheaper and I don't want to spend the extra on the HS20 if I can achieve a similar level of PQ with the Z2. I am also concerned about the Z2 vertical banding posts. best regards Doc.
