I think we have a 144" Camp Chef (or something like that). Personally I think it works great and setup is easy. After about 10 uses, some of the spring clips that locked the pieces together but I think we got good use out of it. We even rented it to friend who used it for movie nights. Our intention was personal so we didn't charge much.

We bought a small rolling rack and put a Rolls Mix Mate 3 along with a BluRay player for the video. We have used streaming devices but they have to be within wifi range. Off the Mix Mate we powered 2 JBL self powered speakers. XLR and extension cords to both speakers. We use an Optoma conference room projector. I believe it was under $1000 and really bright.

It's not something for a non techie homeowner to setup and it's not great for renting to the masses. But it was super awesome for what it does!
