my friends in USA, take a look at local Walmart stores for PowerConf.
use this link with your zip code to possibly find one
Today evening I found 1 for $12 (brand new and sealed) in local Walmart store on clearance section.
This is huge YMMV because it is sold at over $100 at other online and local retailers.
I found this in Unicoi, TN store (it was last one there)
Here is my new PowerConf
