do they have any kind of return policy? if you dont like it, you can return it? if they do it may be worth a shot at trying
They sell their guns for so little money. I don't know why you'd want one that has been potentially trouble for someone else. One of your concerns was getting stuck with a lemon. I'm not trying to be offensive or provocative, I just mean that it you are really scared about getting a bad one, get a new one with a full warranty.
