"Anyway, ABE (cont'd): I am dying to know what power cord you regard as an essential upgrade from the stock power cord, but only costs $50."
J_thunders, no where in my previous posts did I say anything about essential upgrades from stock power cords so please do not misquote me. In most cases I do not believe that it is "essential" to replace the stock power cord at all.
If you must know what power cords I have used, I use mostly the stock cord. But I have built my own using relatively inexpensive parts and cable commonly available from most hardware stores or electrical supply warehouses.
It doesn't surprise me that there are so many outfits that make mega-buck magical high-end power cords. It takes very little (or ZERO) R&D investment, just pretty wires with big gold connectors, some advertising budget, and an audience willing to believe in the magic.
If I buy a fat garden hose of a certain color at 100 times the price of a standard garden hose, will the water coming from the hose magically make my lawn more green? Or will I need a gold plated nozzle to really notice the improvement?
