Well, as luck would have it, our neighbors had a professional painter at their house yesterday so I asked this guy his opinion. He said he uses masking tape, not painters tape. Why? Because he said he gets VERY LITTLE paint on the tape anyway. Like they say, if you want it done twice, hire an amateur. If you want it done once, hire a pro.
THanks for all the suggestions. By the way, it was SEARS paint!
