I agree about the time rake. its insane. It really should be per hand, like max $3 or $4 per hand. The only reason I bring up the $100 or $500 max buy in is that I have played in a lot of them at other casinos (Senaca Niagaga, MGM, etc.) and have wiped up due to the fact that they draw the Donkey $2 $4 and the $4 $8 players. And IMO there is a lot less luck involved in small stakes NLHE.

Get a big stack early and watch your bank roll grow.
