We had a Star Trek Next Generation table in one of my workplaces and that required a technician to service it once every other month or so (it was free play but only a few of us played it much) so you'll need to budget for that or learning to do that part yourself.

Yeah, I can imagine the maintenance would be fun, but I can equally easily imagine that it would join the ranks of disassembled devices and half-finished projects in my garage. I can also imagine that you get into situations where you need a quick $200 or something for some borked part and just don't want to constantly invest in some expensive toy. Or worse, that you need some part that you just cannot find anywhere. After all, they only manufactured a few thousand of the things. Eventually, I assume the well of replacement parts dries up and you're left either custom-building a new troll or castle or just letting your table sit idle.
