We are buying a house and the owners before the people we are buying it off of had a projector and screen. We would like to do something similar but don't want to spend to much on it due other things we want to do first. What are some budget options for this set up? I found a used Dangbei MP1 Max vs 355 and pull down screen would that be a good start?

My pit has super short fur but sheds more than my friends golden retriever. What brush actually works on short coated breeds?
