I am an MF Dealer. The older M6 is a nice unit. It was replaced with an M6s Pre that retails for $1890 so $1500 for an older unit is not a particularly good deal.
It is detailed and relatively neutral. Like most MF products, it is made in Taiwan which results in a strong value. They have been shifting some production to the EU but I don't think this is one of the units that has moved. For the money, it is brilliant.
Most places will give you 10% off and free shipping on a new unit which will put you within spiting distance in terms of price on the used unit.
The other unit I would look at seriously if you can find one is the Ayre K-5xeMP. You should be able to get this For $1700 to $1900 used and it is worth every nickle. I used one for years and loved it. Probably the item I regret selling the most.
