Nah, they're slightly looser for live because it's only 1 table and you tend to have a bigger edge in terms of bb/100 live than you do online.

You also have to take into account expenses. How much does it cost to travel to the casino? To eat? Dealer and waitress tips (assuming free drinks)?

I made a small attempt at this with a $1k bankroll last summer, if just to prove it was possible, but I realized that a good portion of my wins went to expenses and I ended up just about breaking even after that. Considering that the casinos (AC) were about an hour and a half away and while I did enjoy playing in a live atmosphere more, I decided it just wasn't worth the effort until I could play a bit higher except for maybe a recreational trip or two. Maybe your circumstances are different though.
