I agree. I personally dont require it but plenty of people I know do. Just because I dont do it doesn't mean I cant think its a good ideaThis has been covered ad infinitum on INGO, but there are a lot of people that will refuse to participate in a sale that requires a bill of sale or anything recorded. Doesn't mean that they're up to something nefarious. It just means that it's not required by law and they don't want to give their personal information unnecessarily. If you want to require one, that's up to you. Ya pays yer nickel and ya takes yer chances as to whether or not that's a hindrance to selling (or buying) your item.
