@OP you can trace his past escrowed TX's there and after taking a peek on his escrow service thread that will give you a satisfying idea.
As yahoo said, he's been around here for years and also look at his trust, that's how the trust rating system works here in forum. Check out his past deals and history that's totally enough for you to trust him.
You're in good hands with him and I think you should close now this thread.
