Lol...I'm going to have do low end..between waiting on a move, a baby on the way, buying makeup and bags..lol..I've been thinking of the Conair 1875W Ion Shine Double Ionic Turbo Hair Dryer for under 30.00.
If I could get away with $130..woohoo..that's my dream...*drooling*...then I would go for the Chi. It looks like it's a really great model particularly if you are wanting to spend the money for that..lol..For me, meantime, mostly looking for a multifunction hair dryer, with the Conair, I like the fact it comes with a concentrator, finger diffuser (which I would be surprise if I ever use) and Volume pic...as my hair gets longer (one day) I may end up using..but for me..a good hair dryer is multi-functional, effectively dries and styles your hair for the styles you need it, and "feels" comfortable to use.
Biggest thing particularly if you're going to invest that much in a hair dryer..compare what they can do and see if you can find review ratings on them...can't wait to hear what you get!!
