I just got my Garmin 76csx last week and am still getting use to it. So far, so good. I went with the 76 because I will also use it on the boat with the "blue chart" software and on the road for navigation. I'm currently waiting on my TOPO software to be delivered.
I did a lot of research as far as pricing goes and if you have not ordered yet, be sure to check out PCNation.com. That is where I found the lowest price on the GPS unit itself. For software, Amazon.com was the best.
Good luck.
