I see used & broken Hitachi 9 inch Angle grinders being sold on our NZ version of ebay, Trademe.com
They get good prices & a decient amount of competing bidders.

I have about 6-7 of them that i hope to sell soon. They were intended to be put back together a while ago,



& then i found a Supercheapauto.com angle grinder 2nd hand & was impressed with it & its price. Its flaws did become noticed so on buying another one, those flaws were fixed befoe it got used.
Better bolts & threadlocker to hold the head together, spare set of brushes, decent enclosed face disc guard off another grinder. Better 2 pin spanner.
