Which is hair straightner/flating iron is better?

1. Remington Wet2Straight
2. 1″ Pro STraightening Iron- Gold
3. Conair 1.5″ Wet/Dry Ceramic Straightner and curling iron

If you want, you can suggest another flat iron, but please don`t suggest something expensive (like the Brand: Chi)

Suggest something cheap and something that works very well =]
Thanks
Stop telling me to buy a Chi…I don`t want to spend so much money on it. D<
Oh yeah, I have naturally straight hair.
But it`s not that straight, especially the ends. That is why I want to buy a flat iron.
