In general, how "safe" do you think it is to buy a game used bat off of e-bay? What I mean by safe is how do you know you're getting the real thing? I know most players models aren't found in stores so I don't know where else they could come from but the players. Also, I was looking at an Alan Trammell bat on e-bay but the bat has Alan spelled Allan. Is that a red flag? Thanks.
