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

Helo: you are fortunate then to have a reliable power company.  I just installed the Parasound Halo A21, and I have not experienced any buzzing or popping, I am wondering about the possibility of positively affecting the sound stage.  My power company is notorious for surges and outages so it's not just aurally motivated, but protective as well.  I am curious, if it's all snake oil, why would people invest thousands of dollars for conditioners and power cables?

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?

Lots of good advice in there.  I am familiar with Furman, my power conditioning strip is a Furman digital 10 outlet.  I like the idea of something under 5 bills for effective results because that's basically what I have.  I am not familiar with wall warts, unless that is a familiar term for the pucks.  I have already added ground rods outside, one at the AC unit and another at the shop.  The transformer is probably close to 20 years old, so it's a concern, at least to some degree.  Perhaps, the Brick Wall iin front of the Furman and we'll call it good?

OK, let me clarify.  I have no noise, no hum, no pops, no signal induced noise, no component induced noise.  Quiet is quiet, black quiet.  I get more noise from my ceiling fan. (Which is a Hunter btw. ;-) )   Setting aside the consitent power outages, I am wondering most about increasing the definition of my soundstage.  It is pleasantly wide, deep, and high, but can it be improved upon with more expenditure on AC conditioning?  If so, are we talking 4 figures, or something less?  Or this this a moot point, and save my pennies for speakers or a higher end pre/pro?  THANKS TO ALL FOR YOUR INPUT

I must say you folks are very well versed and articulate with what are the potential benefits of a good power condition, to use the vernacular.  I am going to look into several items brought out in these discussions.  I noticed a couple references to not having your amp plugged into a power conditioner.  That seems counter intuitive to me.  I would think that it's one of the two most important devices (the pre/pro being the other) to have plugged in to a conditioner.  Can someone please expound on this?

Hey y'all.  I've come across a very nice Tice Signature Power Block IIIb which I could not refuse.  Now, after searching the internet for days, I've found no owner's manual that is available online.  Does anyone out there have an owners manual you would be willing to scan and send?  It's a long shot, but we have not because we ask not.  I know it's pretty simple, you plug stuff into it, and it works, but there has got to be more to it than that.  I understand the high current for the amps and proc?  But how about the sub?  Should it remain on or be turned off if not in use?  What opinions are out there for using it as the 'trigger' for the Parasounds?  TIA y'all.
