It is an expensive hobby, and many owners I see own a few in their personal arcade space for variety's sake I imagine. Much as I enjoyed The Getaway or Theatre of Magic back in the day, I could not see playing only one or even just those two every single day for hours on end. I know some of the modern tables such as from Stern do have an endgame so at least there is a goal past getting a new high score fun as that can be from time to time.
Although not much can compete with the feel of a purely physical game, I share the inclination of a filthy casual with limited funds to build a digital cabinet. Depending on how minimalistic to moderately extravagant of an experience you want, around maybe a few thousand bucks for materials spread out over time and you can build your own custom rig that plays virtual pinball tables and good for vertical scrolling shoot'em ups with MAME.
I recently found this playlist by Way of the Wrench on YouTube covering what to consider. It is very long to digest. However quite comprehensive and straight forward to everything else I tried watching.
