That last link is Eric Twelker's website, Meteorite Market. Eric is a great guy and a straight shooter. It's not often that one dealer will compliment another competing dealer, but I buy some of my stuff from Eric and he sells some of the best quality specimens on the market. He is a true expert in the field. I highly recommend him and his website.
