The parent site is definitely cool. I'm currently in the position of looking for somewhere cheap to move to and not really having much in the way of geographical constraints, and other UK sites like Rightmove are decidedly unhelpful there - they really want you to commit to an area first. Being able to just pootle around at random zooming hither and yon is nice.
