Walmart offers the Koolscape Fountain Jet 172-GPH Statuary Pump for $17.50. (Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to avoid the $5.99 shipping charge. That's tied with last week's mention and the lowest price we could find by $11. It features a 3-tier water-bell fountain head and pumps 172 gallons per hour.
