My sentiments exactly.I have a bunch of cables from them and also some faceplates. The aesthetics are not as nice as other cables or faceplates but they work. The faceplates are cheap plastic and not the same quality as Leviton, but they were a fraction of the price...
Based on the price, I assume most of their stock is made in China. There's just no way you can get stuff this cheap if it's made in the USA. That said, you don't always need high-quality parts, with the associated high prices.
I get most of my interconnects from Blue Jeans Cable, but my speaker wire, faceplates, and such are almost exclusively purchased from Monoprice.
