depends on how much you'd like to spend

-if you want a high end one, T3 has been raved about a lot.  you can get it from sephora. here's the link:

-if you are not too picky, you can just go to target to get ionic Revlon, or Conair, for very good price. ION helps to create "frizz-free" hair, as I was told.
