I just bought a Micron single-sider stand for my bike and i'd highly recommend it - it's one-piece welded (unlike their conventional swingarm model which bolts together and is also really good) and weighs a tonne. Very reassuring and i'm totally pleased with it.
Make sure you stipulate that it's for a Duke (or whatever else) as they come with a spindle-pin to suit specific bikes.
Out of 5 stars i'd give it 5.
