Perhaps I'm exaggerating. But one of the best things we have purchased is our own scaffold. I don't have the scientific proof - but I reckon it's 500% safer than a ladder and 900% more fun!
Ours is a budget number from Synergy Scaffolding and it is absolutely brilliant. Imagine being able to stand on a flat, level, stable surface 3.5 metres up. Can't picture it? Buy a scaffold :)
Mind you, sometimes you need to be a bit creative and resourceful when you're setting it up.
