My typical set is roughly 1000 chips with the following breakdown:
200 x frac
300 x $1
400 x $5
80 x $2x ($20 or $25)
20 x $100
This can handle 2 tables comfortably, with a rack of frac and 150 $1 per table. I'll buy in the first 5 players at each table with a barrel of frac and a barrel of $1's. once the frac is gone, a barrel of $1's and topping with $5's. next, all $5's and then the $2x.
While I'm not in MA, the most I've ever had in play was 200 frac, 300 $1, 500 $5, 45 $25 and 5 $100
