I got a Brondell bidet from Costco for like $80. It's just the seat and it's pretty fancy slick with how it self cleans and hides/reveals itself while having no electricity going on. Just have to make sure that if you want hot water you'll have to connect it to the sink waterline. I didn't do that and the cold wasn't a problem after a few uses getting comfortable.
Worst case just return it if you don't like it.
