For a 4-chip game, you really can get by with a rack per player. There are people here that will disagree, but I have never been to a home game where I thought "these people need to loosen up!".
If you are coming to
@Seeking Alpha Social Club meetup game in May, I hope that I will be debuting my limit set. I have 940 pink non-denom chips, plus a rack of $25's and 250 non-denom whites. I will probably never use the whites, but it could be fun to use the whites as ante chips for stud games. Totally unnecessary, but it is a chipper meetup game. I don't see the need in having anything bigger....that is, unless you just want to.
Another option would be to buy those leftover China Clays at .06/chip. If you arent going to play limit regularly, you can buy a HUGE set for a hundred bucks. I have a thousand browns that will probably never get used since I just found my dream set. Maybe we can make a deal.
