Hi, I was hoping to get some advice-- I'm considering buying an epilator. 

Are they effective? Terrible? Easy to use? Incredibly painful? Very expensive? Worth it? Am I right in my assumption that they could only be used on my legs, so I'd need to continue using other means on other areas? Is there any point buying one if it's just one more part of a regimen that doesn't really replace another part?

Any comments, advice or recommendations would be welcomed!
