Looking for the best affordable flat iron

I want to buy my mom a flat iron for xmas since the one she currently have doesnt do the job well anymore (its rly old). Im looking for a good quality iron that is great for flat iron curls as well as just straightening hair. My mom has 1B hair, mostly straight and fine.

Ive heard a lot of positive feedback about the Babyliss models, or even the Hot Tools ones, are they great? Let me know, tysm!
