Having just returned to caravanning after a break of a few years, I'm looking to buy a TV with Freeview so I can plonk the kids in front of CBeebies when the going gets tough! I've been looking at all the 15" LCD Tvs on the market that are around £150 and just wondering what the picture quality is like? There seems to be a leap up to about £250 once you get to brands like Sony. Is it worth paying the extra price?
