If you go for the "Wed $30 Super Satelite @ 4:00", you can pick up entry tickets for $20 or less (sometimes as low as $10 for a $30 entry ticket). The players that win tournaments in the previous week win those tickets and sell them for less than the normal entry fee just prior to the tournament, since they can only use one to enter the tournament.
The paper looks like a cheap little things, don't worry you wont get ripped off, nor do you have to do some clandestine deal. You will see old people 15 min prior to the tourney, just ask one of them if they have any satelite tickets for sale. If they don't they will probably help you find someone that does. If not a $30 buy in is good anyway.
Play for fun, just don't think you are gonna bluff anyone. That is a surefire way to loose all your chips there. Be patient, the game will last longer.
There is always a "dealer chip up" option at the table for an extra 1000 in chips for $5 at the begining, it's worth it. I wouldn't re-buy (the whole $30 if you bust).
Remember this, never hesitate to call management if you don't understand the rules or feel like something isn't right. Usually there are no problems but like I said earlier, since all the dudes seem to know each other, they will "gang up" if there is a question. They aren't malicious, just friends.
Enjoy.
