One of my New Year's Resolutions is to heavily increase my monthly savings. In particular, I would like to get a hefty emergency fund since my car is old/high mileage.

That said, I need liquidity.. i.e. may need to drain the account completely if an emergency happens. I looked out at some of the online accounts like E-Trade, ING, etc.. but it's hard to see if you get penalized for going below the interest/% minimum balance.
