Where to get a chi flat Iron??? please answer!?

i am not going to sugar coat this. my Flat Iron $ucks. it is a cheap 10 $ one from Walgreen's, and i need a good one, preferably a chi one. and as you know, these are expensive. i have about 50 $ saved up for one, but i need a little more. my question is: where can i get a super good chi flat iron that will not break, and how much would it be. please answer as best you can. thanks!
