I know a lot of people drip acclimate, but i've had good success with putting a fish in a bowl with all its water, then every 10 minutes i take a turkey baster of water out of the bowl, replace it from the tank, discarding the bowl water. i usualy do this for about 1.5-2 hrs.
i did though see a drip acclimator kit at my lfs so i'll probably grab that next time i'm there.
