Anyone got a good handheld GPS they can recommend? Please note; handheld only. I'm not interested in something that is meant to stick to my windshield. I have a job that requires an insane amount of travel; mostly OCONUS (Outside Cont. USA). So I need something that I can get foreign maps for. In addition to the usual places like many European cities like London, Paris, etc. I also need more remote regions like certian places in Africa, Southwest Asia, etc. The international maps is a must have. Without that, it's useless to me. A topographical map would be nice. Price really isn't a concern as this is something that I really need. I've looked at the Garmin Colorado and it seems like it might be what I'm looking for except I can't find any definite availability of international maps. Anyone got any suggestions?
