What was the price of hair straighteners in the 1990's?

Honey, I'm not a walking encyclopedia, but back in the 1990s, you could snag a decent hair straightener for around $20 to $50. Of course, if you were feeling fancy, you could splurge on a high-end model for $100 or more. But hey, who needs a straightener when you've got that natural '80s perm look, am I right?
