Also, you can buy a damned fine projector for <$3000 if you have a room you can house it in (about price of high end laptop with a better amortization schedule). Throw distances are easily doable for a 12’ span. Shorter throws are getting more common. You can buy a paint system to put a permanent, pro-quality screen up for a fraction of the cost of a roll-up screen (couple hundred plus ur time). Get yourself a receiver and 6 speakers (including mandatory sub) and you’ll be sitting pretty with a 10’+ screen at home. Paint your walls, ceiling of the room black and you’ll have 90% of what you get at the theater minus the people and overpriced food.
