Page 147 Threats of the Galaxy - GH-7 Medical Droid. 6 square hovering speed, 8 strength, medical kit.
Page 103 Force Unleashed - FX-6 Medical Droid, 8 speed wheel, 9 strength, Medkit and surgury kit.
Page 67 Clone Wars - IM-6 Medical Droid, 10 strength, has a surgery kit and medpac reservoir (holds 5 med pacs). While this still fits into the guidelines, this is one of the places where I was questioning the ability to house internally the surgery/medical kits. Reading the description, it mentioned that they carry their own supplies. I also couldn't find anything about a "Medpac reservoir" in any of the books for equipment.
Page 70 Legacy Era - 3Z3 Medical droid, 10 strength, 6 square walking, medkit and 3 medpacs... This one comes close to the load max (25 load, medkit is 20, 3 medpacs are 3 - I'm sure there is over 2 more pounds of equipment on the droid.)
Page 71 Legacy Era - BL-39 Interrogator Droid - 8 str, 1 medkit and 6 squares of hovering.
Page 51 Galaxy at War - A-Series Medical Droid - 8 strength, small droid, med kit, surgical kit, 5 medpacs, 4 movement.
