Don't mind me, but I can't help asking:
Have you considered not using a quarter chip at all -- just using your current Aztars -- by doing the old multiply by four, divide by four trick, and playing your game at 1/2?
In case you haven't come across this before, it means your players buy in as usual, as you would playing .25/.50, for, say $50. But instead of using quarter chips and giving them $50 in chips, you use your present chips, and give them $200 in chips. You then play your game as $1/$2.
When players cash out, you divide their total in chip by four, and give them that amount of cash. So if they have $240 in chips, you give them $60 in cash.
It works perfectly; it gives your players experience playing at 1/2, which mimics the casino experience; and it lets you get more of your $25 (or even $100) chips into play.
If you have, never mind. Continue on with the new quarters...
