I've got 2 sources. This message board is one of them & but my best source is "George Conrads New Issue Service". George sends out an e-mail to all of his subscribers when a chip or chips is/are released in Las Vegas & the state of Nevada. I will then send him an e-mail telling him I either don't want the chip(s) or I do want it & how many. Below is a link to his webpage.
