This was posted by "tapper" for the first mxsl event, but it should be about the same for all of them
"A few things to factor in cost
Events $450 Entry
Roster Size up to 12 players, Avg teams have 10 and a couple staff.
Avg. $45 depending on roster size for entry.
Paint, If you don't have a paint deal we furnish Tournament Grade paint from Valken $40. Special event price only. This stuff is amazing
Race to 4 at 12.5 ROF w/4 prelim matches figure 20 to 24 cases and another 6 or so if you make finals.
Worst case your paint bill is $1200/number of players. or $120 each.
Also I have negotiated a deal with Fairfield by Marriott for $79 double rooms that are very nice.
Most teams report they spent less than $200 total each player to participate in our regional PSP Support Series.
You will not play more paintball in a day for less anywhere!!! Or have more fun!!!"
