If you want heated anything or a blower, you'll first need to consider how you'll get power to your toilet's location. If, however, a cold water bidet is fine then just grab a cheap LUXE.

A TOTO WASHLET is still the gold standard though. That's what I own, and it has been great. Only thing I wish was slightly better was the blow-dryer. The pre-rinse/pre-mist is legit good in terms of keeping the toilet cleaner for longer.

PS - Quick note about mechanical bidets like the LUXE, it has no sensors/safety features. So if a child goes in, turns it on, and runs away it WILL flood your home. TOTO and similar quality bidets automatically turn off the water when weight isn't detected on the seat.
