You don't need 1,000 chips to accomplish this. Me and my gang play casual hold em tournaments about 12 times per year with 8-10 people each time. How is the cash game banker supposed to know how many of those chips are left in the tournament? If they are brought over without being purchased from the banker, who pays when it's off? The banker is normally responsible for shortages, but who would want to be the banker if they can't control the actual bank but are responsible for shortages? Someone you wouldn't want as the banker, that's who!.That problem is completely avoided by using 2 different chip sets.
When that happens, the last players at the cash table discover there is not enough in the kitty to cover the amount in chips they have.
The next color-up will remove all of the lowest value chips from play. As the tournament progresses, chips have less value. These chips retain their value throughout a session. First, I would not get cash chips and use them for tournaments for many reasons.
