If I remember well, last year we had a great CC satelite.
I'm to lazy to search the threads about it, but I believe it was a $5.50 buy-in with 10 or maybe even 18 seats added to a $215 event in which some of the seat winning CC members scored up to I believe close to $800.
Also I know lulu pk used fpp's to play a road of satelites , with which she managed to get into the main event.
Though, haven't looked at satelites yet this year so actually I can't give you any advise, which makes my post pretty worthless except that both examples I gave are prove it's certainly possible to get in cheap.
