I've used GPS extensively while riding and touring. You want a GPS that will be able to take uploaded highly-detailed maps from your computer, and enough memory to be able to store enough detailed maps to cover the area where you'll be riding. I have used the Etrex Vista for several years, but for longer tours it does have enough memory. The Garmin GPS 60CS that I have now has much more memory and the color screen is much easier to see than the black and white. Also the controls on the 60CS are much easier to use while riding. The buttons on the etrex series are small and are on the side. This is important because the reason I switched to GPS from paper maps is that sometimes it's a pain to have to stop and get your bearings and read a paper map. With the 60CS I can easily change functions and navigate with the big color screen without stopping. The legend is indeed a durable, well-built unit that will serve you well, but if you can afford it look at the Vista Color or the 60CS. Magellan also makes fantastic units, especially their color meridian and sporttrack series. Don't forget that CD's containing detailed maps are typically an extra cost, so figure this into your budget as well.
