I do have one of these. I rent, so I didn't get a super expensive one that would require running electricity etc, but it is wonderful. Soooooo much cleaner than paper.

Think about it, if you were to get shit on your hands you wouldn't just wipe it off with dry paper would you? Why do you wash your butt that way? It is completely illogical and very unsanitary.

I bought one of these: http://www.amazon.com/LUXE-Bidet-Vi-110-Non-Electric-Mechani...

$42 installed in 10 minutes with a screwdriver and wrench.

I love it! I wish other bathrooms had them.
