I purchased the Garmin Etrex Vista Cx ($235) from PCntion.com. I was looking for a cheap turn by turn routing GPS. I originally was going to purchase a black and white model, but for $20 difference I went with the color model. The screen is visible and readable in daylight. It does have a backlight function, but I rarely need it. I already owned the Mapsource software ($100). I loaded most of Ohio, western PA, and a route down to MD into the stock 64MB memory card (upgradeable). The routes are turn by turn and if you plug in a destination the unit will auto route to your destination. One warning. If you purchase the handlebar mount ($15), the replacement back does not fit the Cx because of the memory card slot. Garmin tech told me to connect the clip to the existing back and clip it to the handlebar mount. I have taken it on about 5 rides without a problem.
