New Vacuum Regulator

Looking to replace my old vacuum regulator with something a bit newer. I’m seeing a lot of different brands and types with what seem to do the exact same thing, but the price difference is crazy on some of these units.
Does anyone have the “Perfect” unit? Or a huge preference towards a specific brand? Or are there any brands I should stay away from?

What are you using it for? I like the SMC IRV20 for rotovaps

I have a lab society vac regulator $600

Rotovap, buchner, terp trap, oven maybe.
D) all of the above
