Yep. Best Buy over Walmart. Walmart sells some of those items, but they are inferior IMO.Loved the AVR's they used to sell there.
Now, best buy seems to be the only source.
But in most cases these days I just go straight to Amazon to get the technical specs, and just hope for the best in terms of quality and longevity.
Of course since we have an Amazon distribution center outside of town, Nevada sales tax applies on any Amazon purchase I make. "The more things change, the more they stay the same". So much for progress!
