I bought a viper 1200.1d from him.
We possibly had the worst luck ever in the history of sells, mostly through my own fault and little through the postal service. He was increadibly patient through the whole time and kept in great communication the whole time.
Item is in great working condition and he even took the time to help me set it up. A+ seller. A+ guy.
I wouldn't hesitate to do business with him again and I would recommend him to anyone looking to buy something off of him.
