if you want to profit in these games you need to play aggro a bit earlier, and i'd totally recommend buying more chips to build your stack. also call off much lighter, because players tend to go nuts in these things early. adding to that, you really do need to rebuy in these things, set a limit obviously, but you need some sort of limit. This looks from the outset as only a $3 game, but in reality it's actually more like a $15-$20 buyin game, because of the rebuy. if you normally play $15-$20 games, great! if your bankrolled for $3 games then avoid these.
starting with a 1500 stack with the intention of playing tight and chipping up in small pots is not how you take these things down. as bluff said, to each their own, but if you want to make money, you need a stack to play late game profitably.
