depends... a 5 person SnG will basically pay back the person in 3rd, 2nd place will get 50% more then they payed (bout $8 give or take) and 1st place would get something like $12 or $13... SnG's dont take too long if they are only 5 players (i play the SnG's at pacificpoker)... between 30-90 min... it really depends on how tight the players play... if you have 4 fish at your table, you can win in half an hour no sweat... if you have 1 fish and 4 sharks, you will need to play well to win... the $5 SnG's usually have more fish then sharks anyways so i'd go with an average of 45 min per SnG
