New Straightener Help!

So last weekend, Spencer and I went to Washington D.C. for a J. Reuben Clark Law Society Conference. It was fun, and very tiring. WE really didn't have much time to do all the touristy stuff and we didn't even get to do a US Capitol tour. Which I am so bummed about, but we might go back for his spring break. Not quite sure. We were so busy with conference things all weekend, although we did get to go to the Air and Space museum, see the Washington monument and capitol. I also got to go to the Newsmuseum, which was awesome, and wished I had more time to spend there. We got to spend time with my sister, Amy and her fun family. I haven't seen them in 3 years, so it was worth it. I also go to see one my of all time best friend MEGHAN, and her new hubby Joey. That was way way way too short, only like for 2 hours, cause we had to drive back to GA. All in all, it was a wonderful weekend, and a great way for Spencer to learn more about internship process and put his name out there for help to get a job! Anyways back to my hair straightener crisis. I just bought one off of zulily for about $75. I am so mad and upset that it broke. I need a new one again now. I was planning on using this one for about 3 or 4 more years, but I guess I really didn't get that great of a one. IT was a T3 single pass, although it really wasn't a single pass. I really didn't like it that much, but it worked better than my old one that hardly gets hot now and I was pleased to use it for those next years until I could get a nice one. Well now I don't know which straightener to get. I found mine broken in two, I don't know how it happened, but I think someone stepped on it and it broke. I guess that is what I get when its basically plastic, like I said not the best one I've had. So I have used my friends CHI before and have always loved it and thought about getting one myself. There are more out there now that have great reviews as well like the HAI, SEDU, and the GHD? So which one do u prefer, and have you used any of the others ones to really now which is better. I have looked at so many reviews, I cannot think straight and tell which is better. I am thinking I should stick with the CHI, but if there is one better out there, PLEASE HELP ME!
