$20+$2 180 Sit n' Go's

[Hawt]

Hey I finally got my money from Royal Vegas and I was thinking of sort of treating myself and buying into one of the $20+$2/180 Sit n Go's on PokerStars just to see what happens. I only have about 2 hours until I have to go into work though, so from the people who play in these a lot I was wondering how long these things usually run.

Note: Some of you have seen me play in the freeroll and the private tourney, so if anyone thinks I would just be pissing my money away on this since the skill level is a lot higher than mine, please feel free to let me know.
