ebay can be high priced and questionable quality for TG games.
Quality can definately be an issue.  For instance I was just talking to a power seller that has a sealed Somer Assault (I just need the box) and the discription says MINT.  I asked for some more pictures of it just to make sure it was the US version.  The pics he sent show that one of the corners has a huge dent in it.  MINT?  I think NOT.
Just talked to the seller again and he advised he didn't take the pics, his girlfriend did.  He stated it was not dented when he listed it.
