Assuming land use, of course.
In the middle of the Pacific or Atlantic... or just well out of sight of land, the cheapest GPS with no mapping at all is very nearly as useful as the best with mapping... and that's pretty darn useful, if you're in that circumstance. Mere coordinates are a huge help out there. In fact, it makes it well worth buying a cheapie or two as backups... not neglecting the sextant.
