Traded a KRG Chassis and a Remington 700 .308 for a beretta 92fs and $200 cash. Originally the trade was supposed to be for three hundred cash, but I really wanted the Beretta, so I accepted the low-ball. I would give 3.5 stars to the experience- just because of the ease of the trade, the constant redoing the trade conditions, then the last minute decision to not pay me for a gun I got just for him. I'm sure it's just because he's an ODT noob (so am I) and he'll learn the ropes.
HOWEVER, the Beretta I received was in immaculate condition and was in damn good shape. If you want to get great stuff, this is certainly a guy to go to. If I had the money, I'd buy two of his other guns as well because of the condition the 92 was in.
There's no doubt he has firearm knowledge and experience, and I am sure his trade/selling experience will develop with time, as will mine.
