"Are they pretty easy to buy from w/o playing?"

Yes, but the key is to find a table with very few players, and then make sure the dealer you talk to knows that you are toking. You might have to wait between a couple of rolls of the dice until you get what you ask for. Until the other night I had never been refused chips from a craps table in 12 years of doing this. Since the shift boss walked me to the cage to get what I needed, it was ok. Andy - Las Vegas
