I recently discovered that my electric toothbrush was dying and while shopping I realized that I have no desire to pay $200 for a toothbrush then $45 for a pack of refills.

I had an epiphany!

I've been in this scenario before. Using common knowledge I am again in a place where I feel it appropriate to turn my back on the 21st and 20th century. I have decided that I might try natural bristle toothbrushes.
While researching this I have found that there is a small market of "luxury" brushes out there. What I haven't found is anyone spouting benefits or really any discussion out there except the occasional statement of disgust for putting animal hair in the mouth.

Do any of you use a natural or luxury brush? If so, why?
