I have, and use a Garmin 76CS and I could not be happier with it. After doing some research before I bought a GPSr, I decided to get this model.....even before they went into production. They had all the features I wanted AND MORE. They are fairly pricey compared to some of the others, but you get what you pay for. It does so much more than what I ever dreamed of. I won't go into details, but you would be very happy with one I think. It is slighly larger than some of the other models, but it's still small enough to be usabe on a bike. Has a huge amount of memory for maps. I use mine for everything from road trips, to navigating at the lake(boating), to geocaching. I would not hesitate to get another one if something happened to the one I have now. If you have any specific questions about the 76CS, PM me and I'll try to answer them.
