I don't see the point in a setup like that. If you're going to be that cheap/that low volume of air, you don't need a "kit". All you need is a few air hoses. That is a terrible price on really bad air hose with cheesy fittings.
Go to your favorite DIY store, pick out your favorite pipe (anything but PVC) and run some simple lines with $0.50 fittings. It will look better, work better, and probably cost less.
Personally I'm moving my compressors out to my barn, and installing air drops in my main shop. I'll use a 100' roll of 3/4" PEX ($25) and maybe six drops with 1/2 copper @ $8.88 per peice. Add a couple extra bucks for fittings, and that's a full size industrial air setup for almost the same price.
Also from China Freight I'm sure all those valves will soon learn to leak, as will all those push in tube fittings. I don't hesitate to buy a chinese air compressor from HF, but the first thing I do is rip off all the chinese plumbing.
