Hi guys I'm looking for a JQuery Ajax postcode address finder for my customer details form so that they can enter their postcode and a pop-up with a number of suggested addresses for that postcode will show.

Does anyone know if I can do this for free, have already found a few pay-for ones?

Also I imagine there is some way of doing it with the Gdata Api(with GOOGLE MAPS), if anyone has done this can you send me the url to set this up because I find that unless you pass the exact parameters, it's very difficult to get Gdata to work and its very often not the parameter format that the API doc says to use.

thanks in advance
