This is my favorite. $30.
$37 for a cheap, good one: https://www.amazon.com/gp/product/B075MMHQX7/
Totally worth it. If you have an electrical outlet by the toilet you can upgrade to a better one that heats the water. But that $37 bidet is working fine in our guest bath.

Normally it's $25-30, sometimes $20
I got this one: https://smile.amazon.com/gp/product/B075MMHQX7/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 You turn it on by turning a dial, so it's easy to find the right pressure. I used the washlets at Google recently and at max pressure they were still really weak, so I realized that maybe this bidet can be higher pressure than some. Mine is cold-water, but it's really ambient temperature and has never been uncomfortable, in case you've worried about that. It was very easy to install, and I know nothing about appliances, repair, etc., so if I could do it anyone can!
My Brondell has a metal hose and t-valve. I live in an apartment and have never experienced leaks of any kind. It has been installed for a year and a half.
We've been happy with this bidet, especially for the price. Installation is relatively easy and quick.

If you need help finding someone, I recommend Thumbtack to search for people.
