gel, have you considered a samsung 46c750? its 200hz, and is 3d enabled, i know you are not very interested in 3d, but you may appreciate having it, as many 3d blu-rays are the kind of animated movies that you like, its only
£995.95 at richer sounds.
add the 3d starter pack, which costs
£129.95 which consists of two pairs of 3d glasses and the 3d blu-ray of monsters vs aliens, add the samsung bdc6900 blu-ray player at
£249.95 , which has multi channel analogue outs so you can hook it up to you're current avr, and you've got a great tv (the 40in version got high praise and 5 stars in this months mag) and blu-ray player, glasses and one 3d blu-ray for £1379.85..
i reckon that tv would be quite close in 2d performance to the sonys you are considering, reviews are very good, it seems great value to me, to be honest id consider it myself but here in ireland the tv alone is e1450, so its not such a good deal, anyways, just thought id mention it to ya
