It seems as though Korg has shot themselves in the foot with the marketing of the pa 300, 600 and 900.
The 600 came out first at what seemed to be a reasonable price. The pa 900 came out after with additional features for a reasonable price upgrade.
Then along comes the pa 300 which is priced more than a gently used 600.
This did not help the value of this whole series of keyboards as their used value dropped like rocks. As opposed to the Yamaha's...which seemed to have held their value much better in the long run.
Maybe the 600 was a dog...as Frank wouldn't even take mine in on trade.
