Buying a new hair straightener?

i want to buy a new hair straightener. i was looking at the conair infiniti silver nano which is about 100. i was looking on sallybeauty.com and i saw other ionic straighteners for less. i'm sure the conair one is better but my hair is barely even wavy (straightening it just makes it look nicer) but i want to get a decent one that won't kill my hair. if i buy one that is ionic, does that mean it shouldn't damage my hair as much even if it's not over 100 dollars? i'd rather not spend that much on something i won't use every day.Buying a new hair straightener?
ones from sallys beauty are really good. better than conair. read some reviews on a couple on the site. dont get a conair. its not worth it. =]
