need replacement gps

hi, my sat nav has been playing up on bike (seems ok in car) to the point now it doesnt like being on the bike
i was wondering if anyone had anything they wanted rid? not really bothered about make etc, nor it being waterpfoof as it will sit in a peli case on the bars.

thought id ask.
oh, and hate ebay, so not heading there.

Try ebuyer, good prices on there and loads of reviews about the different GPS units.
