Websites for selling houses without an estate agent?

[frogs]

I'm doing the rounds of estate agents for the area we're interested in, but wanted to check out houses that people might be selling privately.

I know there are websites for private property sales, but can't remember what they're called. Any ideas?

we just used www.houseweb.co.uk

or these sites list homes up for private sale:
www.propertyfinder.com
www.fish4homes.co.uk

there are loads of others - try doing a Google search for private house sale
