I have a job coming up with 15' ceilings and will need to put up some walls and drywall. Right now I have one bakers scaffold that has served me good. But I will need to either get another bakers to stack or get a couple sets of scaffolding. The bakers would be cheaper since I already have one but the scaffolding won't be too much more for a couple sections. Just trying to figure out what would be more useful in the future?
