I drip acclimate everything. It's just so much easier than adding some water, coming back in a few minutes and adding more, then repeating again. I can start the drip and then come back whenever the acclimation period is over (usually 30 - 60 minutes, depending on what I'm acclimating). The couple of dollars I spent on a drip acclimater (although one could very easily be DIY-ed) was probably the best / most useful few dollars invested in our tank.
