I did a couple months ago - it's awesome. 30 bucks on Amazon!

Speaking as a hirsute gentleman, the Luxe Bidet Neo 120 has soured me on pooping in bidet-less toilets forever. It's shown me the difference between rubbing peanut butter out of shag carpeting with a paper towel, and that sparkling clean feeling you get right when you step out of the shower.
The unit took me all of about 10 minutes to install on my existing toilet with only a wrench. The easy-to-control flow valve allows you to provide just the right amount of water pressure for a full range of cleaning, from "gentle trickling stream" to "full-on 'Silkwood' decontamination", ensuring the end of your bowel movement leaves you feeling cleaner and more refreshed than using just toilet paper alone. Even flush-able wet wipes pale in comparison.
