Drywall Sander for Popcorn Ceiling

[Ross Y.]

HI Everyone, 

I close on a property with around 800 sqft of popcorn this week and I'm planning the rehab. Popcorn ceiling has to go.  I want to DIY it, but I also want to do it the easiest way :). I've seen some videos on YouTube and read about some people using a drywall sander and it looks like magic but almost seems too good to be true. Has anyone here used one or have any insight on this? I'd love to rent one from home Depot and go to work. 

Hand scraping and spraying water does not sound fun.
