Good place to buy ex-display white goods?

[pandarific]

Just that really - looking for somewhere super cheap to get a gas hob, electric oven, dishwasher and fridge freezer - wary of buying second hand on gumtree as have no recourse if it goes wrong, but would like something decent for the money.

We're in Sussex, but have a car and could travel a fair distance if it'd be worth it!

We bought a Bosch fridge, significantly reduced, which was new but had marks on it. Given that it's always covered in artwork from the children it doesn't matter to us! We found it on ebay - it is a 'graded' product which means new but aesthetically damaged.
