The RZ at our local location constantly has problems and I can't think of anyone who enjoys it. It's been pulled from three of the last 5 tournaments due to malfunctions. Not because of content or callouts or imagery; nobody I know enjoys shooting that game. It's an odd little break from other games now and again for sure. I'll usually play one game of it when I see it working, but not two or three. I would not recommend RZ for location pinball. YMMV, but I suggest you consider other options if money is a factor.

If your goal is to be a spot for lesser-known titles (an admirable, but less profitable goal), then by all means toss it on location.
