Best PPC with good UK network of sites (not adwords)

I am looking to advertise some products for uk only.. So anyone any ideas of good PPC traffic network that has large network of UK sites?
Needs to be something cheap as I don’t expect a huge ratio of sales per click.. and adwords would probably bust the idea by bidding up to $20 + cents a click.. needs to be sub $10 cents..
Have looked at Etology.. but UK network is a bit lame.. something along the lines of them but more UK / Europe focused maybe? If there is such a thing?
