Which of these straightners are the best and wont dry out my hair? 10 pts!?

I was looking in avon the other day and saw a straightner that detangles, dries, and straightnes damp hair. Its called "Infiniti Hair Design." But since its avon I'm not sure if it will be any good. There were also two others that I was looking at. Its called the "Farouk CHI 1 Inch Ceramic Flat Hairstyling Iron" and the "Maxi Glide." Which one was is the best and wont ruin my hair? Please post and I will pick best answer! Thanks so much. And if it helps I always use a heat protector but my mom still wants whats best for my hair.
