...puffy? i use the CHI iron? http://s176.photobucket.com/albums/w172/running_star_2008/?action=view&current=SD532539.jpg
i have alot of hair too but it's not thick it's just alot
and what iron other than the CHI will work one that is less than $100 the CHI cost me like about $120

ya i can see that its REALLY curly but dont be scared just get a straightener that is really good for curly hair.but my friend has hair just like u and she used the Maxi Glide straightener and it looked just like normal straight hair and i am 100% sure it will work on ur hair too

if the chi iron doesnt work for you i would just get it permanently straightened at a salon if you want it straight that bad

and get some layers cut into it too...and side swept bangs it would look really nice
