(if mods will allow this) For anyone considering this - It really is a good bit of kit - I've used it's bigger brother (same everything except a pump system that sucks right out of the can instead of pouring it into the top tray) owned by Eriktheviking and while it might seem pricy, it really is worth it.
You can also get extensions to do entire walls top to bottom without a platform (and ceilings), and larger nozzles (easy to change) for things like masonry paint, as well as smaller to get a better mist for more delicate work.
Overspray is a lot lower than other systems too.
If you've got any large areas to paint in the future, this is THE one to buy.
