It looks to me like one of the so called CT tigers that have shown up in the last couple years. The only identifying feature on this fish that doesn't scream ST to me is the 3rd stripe on the tail.
Now I'm no expert on the subject but I have owned 10 different STs over the years. And as to whether or not the fish is worth $1000 only the op can make that decision.
+1 Except the part about owning 10 different ST's.........
