I know.. first world problems, but I'm still sad about the 640, as it gave me very nice memories, and interestingly it had lot less trouble than the 950 had ($$ fixing, that is)
Another option - keep it and put 17" wheels on it, maybe change the tank and headlight/insturments out for the LC4 version, and then you pretty much have a Duke, but can go back to the 640 Adventure if you ever want to.
Incidentally, I also have a 640 and 950 Adventure - I find them different enough to keep both (for example, a passenger for a long ride on the 640 is not so good, but on the 950 it's quite comfortable), and the 640 has 150+ mile more range on a tank of gas than the 950.
Long ago I learned that I would sooner or later regret selling any bike that I really liked, so I just started keeping them. It's much easier to find storage space than to find a good condition used bike that you used to own and want again. But of course, everyone is different.
