Decision made. I'm going with a 5D2 with a Canon battery grip (I have BGs on my 50D and 7D so I'm used to the feel) and use the $1500 toward new glass or a higher MP FF Canon should one become available in the future. I like the idea of a Digic 5+ instead of a Digic 4 but my goal is to get started in the FF world. The 5D2 is the least expensive way to get a new camera and get into FF. I get a new body every 3 years and who knows what happens then? Thanks, everyone!
Congrats! I think you made a great choice here. The 5DII is a fantastic camera and the AF issue is honestly blown out of all proportions. That centre point on that body is bang on in my opinion. And getting more glass with the rest of your budget will go a long way.
