PMD Microdermabrasion: Effective at-Home Treatment

Are any of you devotee's of Microdermabrasion? While I have always been a fan of a good microderm scrub, I have never had an in-office microdermabrasion treatment. Yes, I have always wanted one. But, never got one for two reasons: I find them to be a bit cost-prohibitive and I have very sensitive skin and was not sure how my skin would react. Plus, I like doing my beauty treatments at home.
