Mine is $10, and the head and batteries is replaceable, but I just keep throwing them out and buying new ones. The heads are like $6, and the two AA are $2 if you buy duracell from like a family dollar, and thats already like $8 right there. So I just throw the thing out and pay the extra $1.50 for a new one. Am I the only one? At $10 I still feel like its disposable. Wish I had $80 sonicare one but damn the unit and heads are cray expensive.
