Those go for $400 - $500 in the states. Even with the freight from Australia it sounds good.

Three-Stage Radiator Cooled...??
- I was just checking back to see what the Chinese compressors are up to. For about $900 you can now get one with three stages, fill rate 2-3 cfm, and top pressure of 4500 psi. Remember the earlier ones used hoses into a bucket of water for cooling? This one has two liquid filled radiators, each with double fans and an automatic shut-off if it gets too hot. 2.5 HP motor and overall weight of 92 lbs approaches size of non-chinese portables.
- I'm assuming one of the cylinders is duplex... One on top of the other.
- And they're actively pitching them for filling Scuba tanks.

-They keep making these better... Maybe at some point they'll be good enough for filling Scuba tanks. The one above has 3 stages... A single cylinder and a duplex cylinder... Which adds up the 3 pistons.
- They're liquid cooled and this one actually has little radiators and fans. Others use a bucket of water and little electric pump.
- But they don't have the air tubing between stages configured in cooling coils. Man, I can see this rig with coils and a fan.
Here's an interesting video:
