I'm going to take the plunge & buy a CHI today.

I haven't researched much since I don't know what the salon has in stock......so I really don't know what I want.
What are your thoughts on the Wet/Dry one? How does it not fry your hair if it's still a tad damp?
Also, are there any heat protectants that won't break the bank? Any that I can pick up at my local Target - without spending $30/bottle @ the salon?
