Just on a whim, I signed up for a little 20-seat sit 'n go last night (3.75 with rebuys and addons). It turned out that it was a super shorthanded tournament with four seat tables. This turned out to be very interesting, and really good practice for blind stealing a sizing bets correctly. The players were almost uniformly dismal (to be expected at that buyin), playing either weak tight or loose passive. I was able to steal blinds and bluff the flop at will, and was given excellent odds to chase straights and flushed by all the postflop minbetting. Anyway, I didn't have to rebuy at all (I intended to double my stack at the start but won the first hand and never dropped below starting chips after that) and just took the addon after 30min. Finished up in 2nd for about $38 or so.
I had a good session at the cash tables too, ending up $100 up or so. Unfortunately I then sat at two very fishy tables late in the evening and pissed away the entire evening's profit on a massive cooler over about half an hour (running at about 30%WTSD and 33%W$SD) *sigh*.
