If you're not covering large areas, a Zip-Up scaffolding in aluminum is awesome. I have one myself with a platform height of 6 meters, reaching up to about 8 meters, and it's 2.5 meters wide and 0.75 meters deep! It's on 200 mm wheels and is easy to roll around at full height as long as the terrain isn't too uneven. Very easy to assemble by yourself, weighs very little, and is stable with a great quality feel = top notch ;D It was a bit more expensive, but it's so easy to work with that it's worth every penny...
