I have the EZ-UP center stand on my SG. I like it because I have to store 3 bikes in my garage and it takes up less space on center stand. Very easy to use...
I bought a cheaper one on e bay few years ago. It was a little bugger getting at where they wanted you to run the bolts, also its the first thing to drag in ally entrances two up, speed bumps etc. plus the threads to adjust the legs were not good or were not long enough to thread it far enough to get the rear wheal to clear the ground when placing the bike on the stand.
I had a generic one on the 2007 Heritage, but took it off and sold it. It was handy to have, but when I turned hard to the left and bounced down, it would drag. Not a good feeling, so off it came.
