Walmart offers the Little Tikes Spiralin' Seas Waterpark Play Table, model no. 620300, for $33. (Amazon charges the same with free shipping for Prime members.) Choose site-to-store pickup to avoid the $4.97 shipping charge. That's the lowest price we could find by $7. It features a Ferris wheel that scoops up balls from a lazy river and drops them off again as it rotates.
