Went instore to Staples (Southport) today and saw a Navman ICN720 GPS on clearance for £69.91.
Don't know much about it to be honest, but details can be found on the Navman site:http://www.navman.com/Navman/Templates/productinformation____12032.aspx
Thought it may be a good deal for someone. THey also had some Binatone ones on clearance but they're cheaper at Amazon. Also, you may have vouchers you may wish to get rid of if you're part of Staples Rewwrds.
