I just upgraded earlier this year from my old Garmin Legend to the newer Legend HCx with the color screen and bought the Wyoming chip for it. It was only $153 delivered on Amazon.com and a friend just bought one there last week for even less. It's all you need, unless you want to spend hundreds of dollars for a lot of bells and whistles that many will probably never use. A lot of people are getting the Oregon model, but it's several times the price of what I decided on. The ones mentioned above are also very popular.
