I guess my point comparing it to a B&M is that ProSlide is the best manufacturer of slides in the world IMO. My point was a two million dollar investment for a park of that size is alot. WnW Phoenix I believe is also a Tornado 45. Though I have only been on the Tornado 65 at SFGAM. My educated guess is that most water single slides cost between 800,000 and 2,000,000 with the clear exceptions being the water coasters.
