I'll stick with my 2-jet turbo for a dependable impact vs the same pressure across 4 jets. I've had 2 different 4-jet rinse tools and the impact cleaning doesn't compare to a 2-jet spinner at the same pressure. I've always gotten more sustainable heat with 2-jets over 4. I'd be interested in maybe a 3-jet but only if the surrounding vac interface was designed like the Turbo. The 4-jet tools are spraying against rushing vacuum; never understood why they haven't improved that.
Far as pricing, I still wear rubber boots when I'm lurking.....
