The SS is a SWFA exclusive. If you get it through Ebay new you are getting it through SWFA's ebay account, which they post on fairly regularly. I haven't had any experience with them, though I have heard that their website is NOT updated for inventory and the only way to know if an item is in stock is to call. Other than that not much bad that I have heard of.
I will say that the SS scope is one I would avoid. When it was introduced it was the next best thing since sliced bread. Everyone on the tactical forums LOVED the thing for the price. Then issues popped up here and there, the fanboys attacked those claiming faults, and things went on. Then more and more issues popped up. I don't know if this is strickly do to volume of a new scope becoming popular or what but I have heard FAR more complaints about the SS line than about that 3200 10x scope. If it were my money I would spend it on the 3200 and save the rest for something 3-5x the cost or spend it on ammo. Just too many doubts in my mind to jump on a SS sight unseen.
