Where's the best place to look for rooms/roommates in the UK? I've tried to google it but can't seem to find anywhere as good as Craigslist or Kijiji which are the best places to look across the pond.

When I get back to England in a few months I don't think I'll be living at home, so I'll be trying to find somewhere in the Manchester area to rent... Probably.

Also, if you've gotten this far. How much about do rooms cost to rent in England? I'm currently paying 60 quid a week in Canada, but I'd assume it'll be more back home.
