I'd like to buy a dryer for my rollersets and I don't know which one to buy. I've heard that some don't dry the whole head of hair, just the front/back. I'd like the smaller kind that you can put on a table and not the standup salon type. Anyway, please give me ideas. Let me know your experience with the ones you have (or have had in the past), which ones I should avoid & which I should consider. Thanks!
