I'm looking to buy an autograph from justdoit23 User's ebay page and just wanted some advice if anyone has brought from him and what people think about PSA DNA. The item I want is listed with a PSA DNA number and that checks out too on the site.
I purchased a couple of PSA/DNA authenticated items from justdoit23 without any problem. That said, you should consider each potential purchase on a case-by-case basis.
I agree. I know you can never be certain but I have contacted the seller and he seems genuine. If people who run popular Ghostbuster fan sites say it looks genuine then I'll go for it.
