I don't have the information to say. I would say that the kit doesn't have to be top of the line gear. The fee would need to cover wear and tear (and maybe a deposit or kicker if someone gets a little overzealous,) hourly rate of whomever is maintaining the setup, plus some margin.

What I'd be willing to pay is something on the order of up to $50 for a session. I think the sweet spot would be $30-$40 for something like 20 to 30 minutes.

There's probably rehearsal studios in the burbs with a minimal drum kit and minimal backline for $25/hour, in San Francisco i remember i being at least 3x that but really worth the money. Part of the experience is going into a dungeon like environment, inhaling huge amounts of smoke and wondering if you'll survive.
