Cheap Straighteners Question??? Please Help!?

I currently own the Conair ceramic 3/4'; straightener that is only worth about $15. I want to upgrade to a straigtener that:

-Is Ceramic

-Has high heat settings (about 400 degrees)

-Will leave the ends of my hair TOTALLY straight.

My price range is about $25 and I have thin slightly wavy hair. This isn't too much to ask is it?

My 1st choice was the Remington wet 2 straight, but I realize I would never use it on my wet hair (too much damage and such). So is it a good enough straightener to just use dry and leave the ends of my hair totally straight?

AND I CANNOT AFFORD CHI. yes, i would love to have 1 but i cant.

Here are the straighteners I was considering:

You are right to avoid using a straightener on wet hair; it will damage it. I forgot which one, but a couple of them have pretty good reviews. Since you are on a limited budget, use the reviews of other users as your guide. You can always return it if you don't like it, and try a different one. Although Chi is a good brand, there are other brands that are just as good, so don't concerned with the brand name. I would suggest that you get a 1'; straightener because it's versatile. The paddle styles are hard to work with, and you can't get close enough to the roots of the hair.
