3rd party maps for Europe, Middle East including Israel


Has anyone had any luck finding a 3rd party map for Europe or Israel? I rented a GPS last year from Hertz and I could have bought a whole unit for the price they charged. I'd love to take my Nuvi with me next time I go, but Garmin doesn't produce maps for everywhere there are roads yet.
One cool thing was driving along the shore of the Dead Sea and seeing the Altitude reading of 450 metres BELOW sea level. It's a long way down to the basement there!
