Overtons.com has a variety of oil suction devices. I bought the shurflo water wolf, which is a 12volt pump mounted onto a 3 gallon bucket, which is nice because the topsider's dont have much capacity. You just hook the little clips to a battery, hit the switch, and it sucks the oil out quickly. Also it's a 2 way pump so you can pump it OUT into empty milk jugs or whatever you use to take it to the recycle facility. It's pretty heavy duty, and i've pumped oil out of my engine red hot after shutting it off(although they dont recommend it) without probs. I still drain the oil the traditional way out the bottom of the car every other time to be sure to get out everything, I'm paranoid
