I've been looking at buying a Toshiba 27WL46 from John Lewis as they are offering it with 5 year warranty for £795. I read the review listings in What Hi-fi Sound and Vis mag but and they give 5 stars to the 27WL46'B'. After sniffing around the web, some stores are listing it with the B and some without?? Is there any difference? If so, what and better still has anyone got one of these? Any good?
