Foxwoods 80+20 noob question.

[tiltaholic]

Hi
I'm a MTT/B&M forum noob. Sorry if this topic is routinely covered (but nothing came up on search blah blah blah):

How do the Foxwoods mtts stack up to online MTTs? Whats the nearest buyin equivalent in terms of the quality of opponents? I'm specifically interested in the Monday/Friday $80+20 game? How many entrants usually sign up? Is what seems to be the oppressive rake worth it?

thanks.
