Some cheap stuff on there, but a lot of it is Beko, Medion or Technika, I'm sure its ok but it is the very cheap end of the market already.

It's worth checking the large electrical retailers clearence lines if you want premium or medium quality brands. They often try to shift their returns at substantial discounts. I've just picked up a Hitachi 22 widescreen HD portable with built in DVD player from Dixons online for £140. It has a very small scratch on the base, you can't even see it. It came with a full 12 months manufacturers warranty, and should retail for about £240 normally.

I've also just picked up a Hotpoint washing machine from Dixons, the best price I could find on line was £314, but the RRP is £360, I got it for £251 from Dixons and it isn't a returned item.

Finally, I bought a LG 100hz 1080 Freesat/Freeview LG 37 inch TV from Argos last week for £399 in their sale. Prices on the comparison sites ranged from £520 to £650.

If you don't mind factory returned items, these people are very competitive too
