I purchased the Mityvac 7400 from amazon do to the fact that i didn't really have anything to lift the car up with and i am extremely afraid of the car somehow falling on me. It makes changing the oil extremely easy, but it does take a while to get all of the oil out. i am still not 100% sure if it is getting all of the contaminants left on the bottom so i think i'll take my car in the next time it needs an oil change.
