An icon of the 1970s, this JVC 3240GM Videosphere space age television is just £1 on eBay right now.
Granted you'll need to get it converted for use to digital (in the UK anyway), but if you can deal with that, this is a fine example. A 'limited' grey version, it's described as being in 'very good' condition and 'hardly used'. A few age scratches being the only issue. But on the plus side, the base and chain are intact.
Not sure how much it will go for in the end, but right now, it's a bargain.
