I got the Cadillac at the start of pandemic. Biobidet BB-600. It's like the nice Japanese ones. My parents have a manually operated one that lets you set your pressure and nozzle positions. Mine has buttons for all of that.
In general I don't support buying cheap shit on Amazon, but I've bought $100 bidets and I've bought $20 ones, and they all do the same thing - spray water on your butt. I had one model that had a hot water input, but my plumbing could never warm up the water in time. So cheap, cold water bidets for me.
No toilet paper at all? So with what do you pat down your wet, dripping butt? I still use toilet paper, I'm just cleaner after for having bideted first
