Quick Take: Panasonic Lumix DMC-ZS19
The Panasonic Lumix DMC-ZS19 is the same as the ZS20, but without GPS.
If you like the sound of the excellent Panasonic Lumix DMC-ZS20, but can live without the built-in GPS, definitely check out the DMC-ZS19.
For $50 less than the ZS20, the ZS19 has no GPS receiver for geotagging photos, but it keeps everything else including its 20x, f3.3-6.4, 24-480mm lens, 3-inch touch screen, and 14-megapixel high-sensitivity MOS sensor.
