Hello Everyone, I have a Wyoming Hunting gps map chip and going to buy a new gps to use it in during our October Wyoming Antelope hunt. I have narrowed down the gps's to the 450t and 550t. I have read that the only difference between the two is the 550t has a 3.2mp camera and I have also read that with the 550t you can take a picture to mark a way point. I have found both units on the net for about 230.00 and 280.00 new. I am leaning towards the 550t, any thoughts on which one to get? Ease of use is my first priority as this will be my first gps unit. Thanks in advance, Kevin.
