Why can't we have these VIZIO LED backlit LCD HDTVs in the UK?

The two models, a 23inch 1080p model (VM230XVT) and a 19inch set (VM190XVT), are both very skinny, offer high contrast levels, efficient energy consumption and apparently deliver quality pictures – just like most LED backlit LCD HDTVs. Unlike rival sets though they can also double as a picture frame via USB connection and like most VIZIO products they are very competitively priced with the 23inch model going for less than $400.
