Was in my local branch of Asda in Bexleyheath and at the entrance they had a stack of 20 inch televisions. Okay if you don't fancy LCD or Plasma.
They seemed cheap enough, only £49, and on the box it did state it had teletext. Could not see much writing about what else it had, scarts etc..
Had a check of the Asda website and did not see any Baier CRT TV
