Just a heads up on anyone considering purchasing an air compressor for use with either a air blasting cabinet or just normal sandblasting. There are a number of "NEW" large capacity industrial air compressors for sale on Aus Ebay.
I have purchased a petrol version -

The seller also has three phase versions -

They are high volume 42cfm (1180L free air delivery) and as they are currently selling for under $1000 each they were a bargain hard to pass up, even with the freight costs they are some of the best priced compressors of this capacity that I have come across.
