Flat irons are the center of my world in the winter. Though I've learned to appreciate my wavy locks, I opt for straightening because my hair is actually dry when I do that and I don't freeze to death every time I go outside.
Good flat irons are mucho expensive. And rightfully so, since they last for years and work so quickly. For a limited time, Beauty Ticket is selling a gorgeous GHD flat iron for $119.99 (MSRP $205)...and it's pink! It's still pricey, for me at least, but it's a really good investment and will save you time and money in the future.
