lol - you sound a little sceptical!!
Most of the customer reviews seem to rate the res, and the whole TV in general, and I'd be amazed if they're out and out lying, but yeah, think I'll ask for a proper demo. The set up was a bit weird - about 7 TV's on display, showing a range of digital, DVD, HD DVD and BluRay.
We were a bit rushed today, should of gone yesterday really, so didn't take up much of the sales dudes time, especially as I knew I wouldn't take one away today. I did get him to quickly bring up menu to see what sort of standard the GUI was, and it was pretty damn high - infinitely nicer than my Thompson CRT (lol, can you spot the budget trend in my purchasing...?!?)
There was an 37 inch 1080p LG in Currys for £585 today on offer... looked quite nice, but Jess didn't like the shape as much as the Finlux. Was tempting with their 6 months interest free credit though..
I might pop over again next week, only in huddersfield, and see if I can get a proper demo going, will let you know what it's like
