Freerolls? Not really, unless you have a good amount of FPPs and you consider those types of buy-ins "freerolls." If you have $20 left, and you want to play low limit, you won't find a problem at Stars. I think the NL goes as low a $.01/$.02, and the limit starts at $.02/$.04. For MTT action, there are buy-ins ranging from $1, $3, $5+$.50 and up.
Being a competant limit player, I would suggest taking the $20 and building it at the $.25/$.50 tables.
See you at the tournament.
