Love my pletscher. Installed one on one of my recumbents (a great bike to go bike touring with), and I love the fact that it swings up and out of the way out of the chain drive line. Cost a bit of money, plus I had to cannabalize some tubes to make some support plates for them, but I love the result.
My dahon curve d3 has a standard dual kickstand. Seems to work just fine, but it does tend to rattle a bit as I ride, and I might be concerned about clearance with the chain. YMMV.
