Having used both, I'd disagree with the person who says there's a learning curve for gas smokers. Today, for instance, I was doing a Butt. Other than mopping and adding water and wood, it was as simple as simple can be. And, with a gasser, you can bring the temp right back to 225 with a flick of the wrist.
Get thee to Wal-Mart and get a propane GOSM for about $100.
