I used these guys for ds's bedroom a couple of years ago. Takes a little while to arrive but you can choose from lots of different styles/grills etc. You can also get a white or Barley cream painted finish.
We went for a white painted finish and still very happy with it 2 years on, not sure what an unfinished wood finish would be like.
We got some from MDFWorld.co.uk, they make to measure as well as have some standard sizes. Very pleased with the hallway one particularly as it has a big mirror over it and now there is somewhere for dd and i to leave makeup for last-minute perfecting before we go out
