I bought a Yamaha Seca II 19 years ago, rode that until I got T-boned in an intersection in Detroit (totaled the bike and me), then I got a used TDM 850 in 2000 when I was stationed in VA.
I sold the TDM when I was transferred to Shanghai, China. Bought an electric scooter in Shanghai (motorcycles are banned in Shanghai- unless you have one that is grandfathered in before the law was enacted), rode the scooter in Chinese traffic (very scary) for 3 years, then was transferred to Beirut, Lebanon where I rode nothing for two years.
I finally bought my Busa in '08 when I was stationed in Seattle, and have been loving it ever since!
Now I'm stationed in LA for the next two years, then my wife and I will be transferred to our next overseas posting. I plan on bringing my bike with me unless we get stationed in some country where they are banned or we are stationed in some shithole.
