I found the play between the $1 SNG and $2NL to be very similiar. The difference was that variance for ANY tournament structure is generally higher than a cash game. Next, I remember the rake structure to be particularly bad for $1 SNG @ +$0.20. You're giving 20% of your buy-in to the rake right off the bat, whereas cash games seem structured better. If you can consistently beat your opponents, then it isn't so bad, but pretty much EVERY SNG I've ever played has many flips and a 60% edge may seem pretty good, but it loses to 40% enough times to make for some pretty swingy results.

Again, if someone really LIKES tournaments and SNG's, I say go for it. But, I started that route, had success and still strongly believe cash is a better way to build a roll and make a living in terms of learning the game, minimizing variance, and results.
