My general opinion of estate agents is unprintable. Credit where it's due though, George Proctor & Partners were nothing less than totally professional when I bought my place.
Property World have a good reputation locally - they are totally committed to the area and get a mention in the recent Time Out article. They claim to be the area's 'independent agent' and have a special offer on at the moment for sellers - go to http://www.propertyworlduk.net/main.htm
Found Proctors at the end of Silverdale/High Street good. Some estate agents can be a bit, 'know wot I mean 'guv' but they seemed quite relaxed and un-pushy.
