we bought it at xmas in the 1/2 price sale
and i fitted it myself with a little advice from a mate.
only thing i wont do is cut the joins on the work tops, a mates doing that for us (hes a joiner lol)
plus our parents gave us some money towards it at xmas to buy it, instead of prezzies for us lol
ps mine is 450mm above the worktops as they were 100mm shorter than the old ones (so in the middle of the old units they have 50mm top and bottom)
