The entry fee is the same as it always has been.
I don't think I have seen a tourny entry fee of 10% on a $60 buy in tourny for years.
$6 juice will not pay the dealers, much less floor help, drinks, supplies, etc.

There is a big difference between putting on a private tourny and running a small buy in daily tourny for 20 people. Most casinos won't touch a private tourny for less than $50 each entry fee. I do private corporate tournys at the Palms every week. Normal charge for set up and operating a 15 table tourny is $7,500 Mon-Thur. You don't want to know cost Fri-Sun. $2,000 of that can be used for food and beverage. After $2000 you pay more.
