Seems like an amazing price - much cheaper than elsewhere! Free delivery!
Reviews are brilliant - a very useful feature to note is the ability to play back divx files via usb - half kicking myself for buying the bargain 42LD450 (without freeview HD and Internet) that was on here a few weeks back!)
This tv is 50hz and uses 134Watts which is about average for 2010 LCD tv's.
Richersounds will pricebeat by £10 to make it £388.99, you may be able to get a 5yr warranty for 10% extra ontop of that or 10% more than £400 so £440. You might be able to get £10 off instore by printing out this £10 VIP voucher after registering: http://www.richersounds.com/viplogin
So possibly £430 or lower with a 5yr warranty.
This tv can play Divx .avi, x264 .mkv btw.
