I am going to buy one but I don't know which one to get. I was looking at the new ones and they say things like "the size of a deck of cards". that is cool for a camera but I don't want to be squinting and swirving while I am trying to read this thing. I drive an SUV, it is ok if it has some weight to it. Can anyone who has one point me in the right direction of which one to get.

Thanks,
Noob
