I have appreciated all the input. This is a really friendly forum. I decided to cool my jets for a while, take a couple of motorcycle safety courses and perhaps the rawhide adventure course then consider buying an F 800 GS.
A big shout out to Eric at Sandia BMW. He seems like he would be really easy to work with. If anyone is interested in an F 650 GS check out the one at Sandia BMW in Albuquerque New Mexico. You can tell him Mark recommended him. That may give me some leverage when I make a deal a few months from now.
