Clarisonic: To buy or Not to buy

Really debating on if I should purchase the Clarisonic or not. There are such great reviews on it on the web, whether it's from Makeupalley, Sephora, or QVC. I have always wanted it but I just never got to purchasing it because it is so expensive! I just want to see if it lives up to its hype and helps out my skin. I'm leaning more towards getting it but I do have a guilty purchase conscience. Any of you have it and care to share your story?
