Thank you everyone. These are the ones I see most mentioned on the forum.

T3 Featherlight
Metropolis Z-Ion
FHI Nano Salon Pro 2000
Babyliss Pro

If you have one of these or even any others please let me know. I do not straighten my hair so I am looking for one to use with a diffuser.

Pro's: very light weight, the technology really does make a difference in frizz, can purchase a diffuser that attaches directly to the dryer.
Cons: didn't dry quickly and not as durable as it should be for the price. Even though you can purchase a diffuser that fits it, it should come with it for the price you pay.

FHI Heat Nano Pro 2000 FHI Heat Nano Salon Pro 2000 Professional Salon Hair Dryer With Nano-Fuzeion Technology: Beauty
dries my hair quickly, frizz free, very powerful, speed and heat control, diffuser comes with hair dryer and snaps in.
have to be careful not to drop the diffuser on the floor, because the teeth will break.

T3 Featherlight
I have never had one, but a friend of mine did. Her's overheated several times. For the price this should not have happened. She prefers my FHI hair dryer.

Babyliss Pro

I tried it - returned it.
Wasn't powerful enough for the money. Nowhere near as good as the Metropolis or the FHI hair dryer.

Deva Hair Dryer
Terrible hair dryer. Diffuser was brutal. Broke up my curl pattern, created frizz. I use it for my dogs.
Type: 3a fine & dense,with normal porosity, terrible product junkie
ROUTINE: LI, enhancer, gel, plop with Curlease towel, serum product (either CIAB or Gel-les'c), clip & diffuse.
Too many favourite products to list ... I finally have my routine that works and alot of products to choose from. My product stash is huge, but well loved !!!
