Fun idea

Well then if you are not afraid of tinkering creality printers are great to dip a toe at that price point and also serve to give you a solid foundation of the hobby. I started with a standard ender3 and then upgraded for a while as I learned more and finally have settled for now with a bambulab.

I think it would be better to say what your budget is since entry level is subjective.

No idea. I also have a backbone and use it for steam link games with great success and there are several games that have native phone support for it.
