LuxeBidet is the model I got.
Totally entry level, hooks up to the water supply to the toilet tank. No heat or special features, stupid easy to install. Price around $50.
To my mind, no need to go more expensive until you know more what you might want.
I do have an aunt and uncle who got an expensive toilet bidet unit with heated seat and all the features... after having tried my bidet while visiting.
Plus with the cheap unit you get the bonus of hearing the startled yelps of your uninitiated guests as cold water hits their asshole for the first time.



My wife and I started Widow's Bay and we are loving it. She typically doesn't like horror and it is too much horror for her.
But the humor softens it a little, and she enjoys horror a bit more since we got married as she just feels safer. (And yes that warms my heart.)
