The problem is at $50/month+ the service expectations become much more expensive to provide -- even though a dedicated member could get it back into the 30s.

Edit: what I mean is that if price ranges from $30-60 the average cost will be a lot nearer that range that's perceived as upscale gym. Whereas ranging from $0-60 would at least appear to be nearer the ordinary $30/month average. It would entirely depend on usage, obviously.
