Bauknecht, Siemens, Whirlpool, Bosch, Smeg, Hoover & Servis all to black washing machines.
Have a look on the UK site pricerunner.co.uk so you can get an idea of prices too and see pictures of what they look like.
littlewoodsireland.ie have the Hoover and Servis washing machines in black and they have a Servis dishwasher in black and you can order on line which is even better.
the look pretty cool on the screen.
