What is a cheap, nice smelling and well working heat protectant that I can use when straightening my hair?

Personally, I use the Got 2b Smoothing Lustre Lotion.  It smells wonderful and it works great when I straighten my hair because it prevents fly-aways and it has a uv protectant.  Walgreen's has a sale right now for 2 bottles for $5.49(or buy 1 get 1 free).  

"This decadent lotion infused with luxurious cashmere, shapes, smoothes, control fly-aways and imparts an amazing weightless lustre and softness. Helps to protect against damage from heat styling and contains a UV protectant".  

I have listed some other options below that had good reviews on other sites.  Thank you for your question!

I don't personally use a heat protectant but I have watched my wife work on her hair and a great scent is so important.  She has used Heat Protexx® Heat Protection Styling Spray which is an alcohol-free styling spray that aces as a barrier to absorb heat and prevent breakage for a smooth, frizz-free style. 
Now the John Frieda Frizz Ease protective spray straightens strands for up to 24 hours; helps block humidity and rehydrates.  It also has a very light scent to it that lasts for hours.
