I'm getting the idea that Maytags are hard to find over
Generally people, who own Maytags over here, tend to hang onto them until they break down irreparably. That's why they don't make it onto ebay that often. They are around and, like Speed Queens, people wanting something a little better than average bought them. They are/were common in commercial settings like medical centres, shops, residential care places etc. and laundromats. They are not that hard to find, if one really wants to find one, but also not as common as they are over your way.
Converting AUD 152.50 comes to approx. USD 160.00.
If spinspeed is really keen on this he should go and check it out. They are very good machines and if this one lives up to expectation, with no work required, I'd go as high as $130.00.
