Get the Honda
Siyeh: Of the three scoots you listed, I'd get the Honda PCX. Resale value would be better with the Honda, then of course there's the out-of-this-world mpg.
I was considering the PCX when a very lightly used Honda Sh150i popped up "used" at my Honda dealer. As long as you've got decent roads, the PCX should be a winner over any other 125. Good luck!
