Hey Captn,
There were a few players who chose not to rebuy or addon whatsoever. I don't know if some did not want to pay or could not pay, but they didn't. I know for a fact that one player who didn't rebuy/addon was a big chip leader, having won a 3-way all-in early in the tournament (AA v. KK v. JJ). He ended up winning the tournament, and spent only $10 to earn $200.
I approached the change to a rebuy format like this. We typically get about 15 players to this tournament (sometimes 4 events per month, sometimes as few as 1). Of those 15, 6-8 are regulars. The regulars want to play for higher stakes and the newbies don't. The newbies also don't want to blow $10 in 30-45 minutes. So I basically told the better players that
A) rebuys/addons meant more money total to win from the newbies
B) they can recover from early bad beats against the noobs
I told the rooks that
A) They could be more aggressive early on against the better players
B) They would be able to play longer
As it turned out, the eventual winner (a veteran) earned more money, tripled up on two noobs, and they got to play more after a tough beat.
That 16-man tournament was last Wednesday. We had another last night. It drew a record 24 players split over three tables. Many of the guys were new to our tournament and liked the structure. We had
24 players x $10 buyin. 18 rebuys x $5. 14 single addons x $5. 8 double addons x $10. Total prize pool 240+90+70+80=$480 (very large for us). The payouts were
1st $240
2nd $120
3rd $70
4th $50
I purchased one rebuy and a single addon and ended up placing third in the tournament for a net of $50. I felt good about it because I lost a big pot early on with AsKs on a board of 10s-Js-6d. My opponent went all-in for about 1500 and I called. He had pocket Queens. Turn and river were 2d-4c.
It was basically twice as much money as our old tournaments and ten times more action

. I look forward to more of these events in the future. I will let you know if we change anything.
Keep asking questions, that's what this place is for.
