Jumping on an old thread. I purchased a Harbor Freight Oil Extractor and used it to change my oil for the first time. I will NEVER go under the car again to change the oil. Worked Great. Fed the tube in the dipstick hole and pulled a vacuum and started removing the oil. I then went to gather all the oil change stuff (minus the drain plug wrench). Took about 20 minutes to remove the 75F oil. Extractor holds the full volume. Cleanest and easiest oil change I have ever done.
Here is the link for the oil extractor. Coupon for July reduces cost to $79.
