I guess I'm just cheap, I am equating a $140.00 air pad to $150.00 tenni-runners that might only cost $10.00 to produce,

When I bought my airpads I got them on sale for <$45.00 ea., 2 years ago, insulated and non-insulated versions.
I wonder how effective a non-neo pad might be if it was backed by a layer of needle punch reflective insulation, reflective nylon or just a space blanket?
