Unless you're unwilling to compromise on screen size or have some other extreme edge-case deal breaking scenario like needing the center-channel behind the screen, a projection home theater doesn't make sense. It's a waste of money and it's worse in many ways.
A lot of hobbies are like this. The expensive stuff there for some stupid reason people won't compromise on.
@SwiftOnSecurity In my case, I didn't want something heavy on the wall, and I found a QKK for $25 barely used. HDMI, USB, VGA, and it's tiny, and portable. All I need is a darkish room and a white sheet on the wall and I'm set. Bluetooth headphones connected to the source video is a bonus. Cons? Unless it's nighttime or you use a window blackout, it's subpar experience, and the fan in the unit is a little noisy. A ventilated projector box failed to keep it cool enough so I had to replace the lens inside that got imageburned, replaced that for about $7 and everything was peachy again. But for a home theater, yeah... the room has to be super dark or it's not that great.
@SwiftOnSecurity and those little Roku boxes wow they get hot too!
