Which microdermabrasion kit would be the best to treat acne scars?

None: Microdermabrasion is a fancy way of exfoliating dead skin and will do little for acne scars.

Microderm won't work: Microdermabrasion just "buffs" the skin and doesn't result in any change beneath the surface. You need collagen formation to improve acne scars and this will only result from laser resurfacing, dermabrasion (aggressive sanding of the skin) or a chemical peel.
