Reply to Good deal? Xone DB2, 2 - DN-S3700, SL2 and Maschine MK1

Found a deal for the following. Now from what I am told everything is A1 and mint. Price is $1400. Good deal?

I have an MK2 Maschine on the way, and really don't use Serato but is this a good deal and would you purchase if you could? What do used S3700's and a DB2 go for?
