Live NL - How much of a disadvantage do I have?

[BigBluffer]

Florida law limits the buyin to a NL game to $100. If I get to the poker room when all the games are well under way, and 3 or more players have stacked up to $300-500, how much of a disadvantage will I be at coming to the game with just $100? I'm talking about $1/$2 blinds.

Should I just forget about it and make it a point to get there when the room opens so I'm starting on an even playing field (at least chip-wise) with everyone else?

I'm trying to transition from LHE online to live NLHE. Reading this forum and some books, as well as practicing with low-level NLHE online and Poker Academy Pro.
