Hi All! Since reading all of you rave about your GHD experiences, I am going to get one. BUT--what is the difference between the two? I read the descriptions on sephora.com,and it appears that the iron for $195 does not have a fire retardant casing??? Am I missing something here??? Is the $195 one going to go up in flames??? I'm seriously confused and don't know which one to get. TIA!
