Projectors have gotten much cheaper in the past few years (I used to look in awe at some of the incredible creations on the now-defunct lumenlabs forum at the DIY creations people would build because of the high projector cost back about 10 years ago). You can buy a very capable 1080p projector for €450-500 or so. You can build a high quality DIY screen if you're so inclined too. It's a bitch to setup, and you have to hide the power and HDMI cables somehow, but the experience is unbeatable.
