I like the look. Power is iffy but should be easy enough to handle with my newbie riding skills. Downsides I can find are it's a bit heavy (445 lbs dry) and a vibrates a bit at highway speeds (so does my GS  though so hey...).

I looked on ebay and they seem to typically go below book value, if it goes cheap enough I'm tempted.
