I'm trying to do it on the cheap. I already have a projector. I see a lot of under $200 inflatable screens. Anyone used one? I image we will only use a few times a year so I'm looking for something easy to set up and store. I also need to take care of the audio side. I really can't pull out my main system L/R speakers so I would probably be looking at some inexpensive DJ type speakers on stands, maybe self amplified. I'm hoping to do those for approx. $300. Any suggestions?
