I was recently offered the same thing from another member. A completely built, ready to go, 3.8 off-center stage motor.
And as much as your offer may appeal to me, I must regretfully decline.
It was offered to me in private. So, I just sent a PM out to him about you. If he's still interested in selling, I'm sure he'll get back to you. If not, reach out to Fat Nat above!
