No hate here. I have a 615 and I feel like I got what I paid for (didn't pay sticker). It's a nice mando but I've played better, include some other Eastmans. There is some sloppyness in the workmanship and such. Not unhappy with it, not terribly thrilled with it. My Kentucky 380s was much more bang for the buck than my Eastman. A third of the price and sounds slightly better.
Played a used webber the other day and an old montana flatiron. That's where I'm headed next.
