Anyone here who has a kickstand on their bike, what brand is it and where did you buy it?

I noticed some kickstands mount near the crank while others are rear-mount. Of the latter, will this interfere w/ trailers that attach to the rear?

A search on Amazon reveals the "Greenfield Stabilizer Rear Mount Alloy ATB Kickstand" to be the most popular. http://www.amazon.com/Greenfield-Sta...5315140&sr=8-2
