It is $100 a week or $300 a week? What limits do you play in your cash game? How big is your roll?

If you are making $300 a week from the same players, I would stay right there, seeing as it has to be easy money. If it's $100 a week I would consider cutting back a day and playing that day at the casino if it's close. Without the answers to the questions above it's really difficult to tell you what to do. Just remember this, the casino will be harder to make money at than your local home game. The players will be better and more apt to change their style of play. I've found that different levels bring different challenges and pitfalls. At higher levels the players can be better at playing sets to where you don't know they have a set. On top of that, they are more apt to not chase draws without the odds to chase. You might see it take longer to make the same profit, even at a higher level.

Another problem with the casino is that every hand they take a rake and any jackpot bonuses from the pot. In a home game that doesn't happen. You might want to try the casino one night to see how the quality of play is. If it's better than you want, stay at the home game. If you feel you can run the table at the casino, then go there as there is potential to make even more.
