[TheForge] Little genie unloader valve

[Shannell Sugrue]

After recent discussions on this list Im going to install an unloader valve
on my compressor. This is the gizmo here at top of page
http://www.grainger.com/Grainger/catalogpageview.jsp?xi=xi&CatPage=2792
I can get one here in Adelaide for $100 USD, which Im not prepaired to pay
when they are listed by grainger as $33, thing is grainger want $55 USD to
ship it to me, which is a joke, Ive bought a lot of stuff from the states
and know it should be more like $15-20 USD. My question is, after all that,
anyone know of a good online supplier where I can order one of these from?
preferably somewhere that doesnt put markup on their freight charges :)
