Before you guys purchase the Quest, you might want to check out the Garmin 2610 -I compared every GPS available before buying the 2610.
I have had a GPS for years(this is my 5th unit)& the 2610 is amazing. Here is what a test I read said about the Quest:
"The Quest is basically a miniaturized, reduced feature, reduced screen size, non-touchscreen, smaller map memory version of the SP-2610"The touchscreen feature is awesome in the 2610, after using it this Summer I would never buy a unit that didn't include that feature. With the Quest, if you want to "look ahead" or around you at surrounding roads on the map, you have to scroll to the edge of the map with a rocker switch, wait for the screen to refresh & then scroll again. With the touch-screen, all you do is touch the screen anywhere with a fingertip & then slide your finger across dragging the map along with you(the 2610 is faster than the Quest & refreshes almost instantly)
Here are some test that might be informative to some people trying to decide on a unit:
