Sometimes I think too much about making a choice -and this is a classic example. So I decided I WOULD go for the Panasonic TXL42ET5B having found, for me, a deal I was happy with from Richer Sounds.
£799 + free 5 yr warranty; the deal was also supposed to include a BD Panasonic DMP-BDT120, but they were out of stock, so for and extra £30 I got the upgraded BDT220. And they refunded my £1 parking
This replaces a Samsung 32" which will have a new home in the front room, and so far, I have absolutely no complaints at all. Bright, clear pictures, no artifacts or smearing (yet) and the 3D is pretty impressive on BD.
So I now have a passive 3D to complement my active 3d Panasonic PTAE5000 projector
Still, the idea is to have something for whole family that's easy to use every day - and it won't be the end of the world if my 6 year old breaks the cheapo specs either.
