I used to a source 4 Leko and down is the "real way" to do it, but I bought a good projector and lever looked back. 3000 lumens minimum and it's plenty bright.
Being able to make your own gobos, and even in color (if I want) goes a long way!
When shopping for a projector, make sure it has horizontal and vertical keystone so you can fix the distortion it will have if not optimal placement.
I like NEC as a brand for projectors. Very good picture and exceptional reliability.
Super easy to mount into projector crdble made that attaches to photo light stands-can be raised upto 10 feet.. It's super easy.
Also regadrding the media source, you can use any tablet's display connection right into the projector, so all you need is power drop since the tablet sits on the projector itself.

Also, this is a super easy way too--https://csnl.com/products/video-projector-mount-systems
I just prefer he ones that just allow strap, although not quite as flexible as the CSNL mount (tilt wise). It's justs so darn fast to hook it up since you are not threading anything to a mount.
I still say get one with a connection that will allow it to adapt to a light stand.
