Jumping in on the conversation so it's in my topics list.
Pending price, I'd consider getting this. Less than $500 would be where I'd be interested. $500 or more, I think I'd rather consider looking for a fixer-upper machine. While the footprint is smaller, I'm sure the width isn't all that much different, and would take up around the same spot I'd put this or a real machine.
I did see a video where someone plugged in their Switch into the other virtual pinball machine (forget what that one is and too lazy to google right now), so they had the full set of Zen tables in vertical mode. So I'd think even if this is shipped with a set number of tables, shouldn't be too hard to convert.
