I just bought my very first GPS and the number of options from Garmin is just crazy. If you think it's confusing for you guys... imagine how confusing it is for someone buying their first unit who doesn't know the first thing about GPS units! You almost have to hire a full time research assistant for a week. There are what... seven eTrexes, nine Oregons... four Colorados... three 60's. And they're all almost identical. And why... in 2010... does anything come with a black and white screen? Really. I also love how you'll compare two units and find out that the only difference (aside from a $100 jump in price) is an SD card slot and a digital compass. The same unit basically. They just didn't solder on the 25 cent SD card slot and compass chip. And they charge an extra pile of cash. They really need to simplify. Take a page from Apple's book. When you buy an iMac... you have basically two choices... big or bigger. There should be no more than two models in each line. I'd say.
By the way... I ended up with a Dakota 20. Love it so far. I chose it over the Oregon for it's small size and weight. I want to use it in as many scenarios as possible so it should be great for that (hiking, biking, running, backpacking and search & rescue). A lot of SAR folks use the 60... but I wanted something small and intuitive that would be lightweight and easy to use for other activities. I would never take a 60 on a 10K run for instance. LOL.
