One thing I've learned is that whatever you decide on, you will be disappointed in 2 years because you will be able to get a much nicer graph for the same money. I guess a lot of technology is that way though. I bought the Garmin 93 SV last year and I've been really pleased with it for the price. You might want to shop around for a used unit. After a year or so you'll have a better idea of what features are important to you, and the units you are looking at today will be $100 cheaper.
