If you go for one of the new V20 models watch out for the buzzing sound they make. You get used to it but it's definitely there.
I've done a bit more reading about various issues and so far it's shaping up as:
G10 - great unit - shame about the unwatchable 24p flicker.
V10 - great unit - shame about the automatic progressive loss of black level.
The 50V10 [$2.4k] - I'm quite disconcerted by the floating black issue - there are a lot of pissed off people out there.
Dunnersfella: Here's something to ponder.
Do you believe that... without actually reading the reviews on-line... that you'd ever notice 'floating blacks', dropping black levels or indeed 24p flicker?
samwooff: Why not a 50" U20? It's performance will be better than the G10 and similar to a v20 in a dark room, the V20 smashes it in a light room though due to the better filter. To avoid the black level loss you can also go for another brand of plasma...
There's no sat tuner on the G10 sold in NZ.
Me personally, I have a crush on the 50" V20 and am trying to come up with a devious scheme to obtain the funds for one :P
