Generally, the pain is greater from a tattoo if there isn't much fat in the area. So a tattoo on the foot/ankle would hurt more than a tattoo on the stomach. Autoclaves are a standard piece of sterilization equipment found in hospitals, nearly all laboratories, etc, and I'd run far away from a tattoo parlor that didn't have one. They have big bottles of ink, and squirt what they will need for the tattoo into little cups, which get thrown away after the tattoo is done. When I got my tattoo, they gave me a new tube of Neosporin ointment to use on it for a week or two.
