I know that MM have a pretty huge reputation around Australia for making quality gear, but they have always been pretty hard to get hold of. My MM5 took about five months to get here, and the guys at my music store told me that was pretty quick!. Apparently there was a problem with the Australian distrubtor for a couple of years and they changed distributors late last year, which is now helping the basses come into the country a bit quicker. I was actually in a band that got a MusicMan endorsement from the new distributors last year, so they must be pretty cool!(the distributors, that is!)
Second hand prices for MM basses in Australia are still higher than buying a brand new Yamaha - mind you, thats apple and oranges!
