How much should a person spend to get a decent power conditioner?

Thanks, helo.  I'm sure I will get varying opinions, but I am going to seriously investigate Brickwall unit.  I did  not see any prices in the link, maybe I just missed them.

On a complete sidebar, a helomech sold me my motorcycle. You don’t happen to live in beautiful Cenla do you?

@helomech- I believe the brick wall technology was developed by Zero Surge out of Frenchtown NJ, who sell their own units, from two outlet jobs to industrial sized panels. 

First you have to decide what your needs are. Do you want surge protection with some filtering to reduce some extraneous noise from your AC mains and components? This is passive conditioning.
Or do you want a power regenerator which takes the incoming AC from the grid and your service panel and cleans the signal (reducing noise) then regenerates a new sine wave to power your components, (Active power conditioning). These are needed in areas of an unreliable power grid or excess noise from old power lines and transformers, or areas of heavy interference.

The archives are full of threads with recommendarions.

Specifying your budget will help, but it also lends itself to defeating your Thread Title.

I'm curious about how best to treat my AC and stay within my budget.

Every power supply/conditioner I have had, across multiple locations/states has yielded improved performance (from lower cost to moderate/higher price points) in each system setting.
