We're now officially into super-size territory for TV screens. Any used 70"+ TV for sale is mammoth in size. Buy new and it will come at a mammoth, jaw dropping price too, well into the thousands, typically.
This is the top premium range and you can expect premium prices too. This, of course, means considering a second hand 70" + TV for sale should save you a great deal of money.
For the simple reason that few of us have living spaces that can comfortably accommodate a television of this size (and the aforementioned prices), there is less to choose from in this range but what is there to be found will be of exceptional quality and performance.
Prices vary quite a lot for TVs of this size as well, so (as is always the case), it's worth checking out the original RRPs and specifications of any model you might be thinking of buying second hand. As an example of the differences in prices, Sharp's Aquos LC-90LE57K is a whopping 90" screen which will set you back around £9,000 new. Meanwhile, Sony have an 85" model (Bravia KD-85X9505) on the market for £20,000 - so it's definitely worth doing some careful research.
