I ditto what Tropicexotic said. I used jetset and not only was it by far the fastest for setting, but dry time was much faster.
Magnetic rollers are tedious to me and my back kills me by the time I get my whole head done. Of course it takes forever for my hair to dry. I never really mastered the whole magnetic rollersetting thing.
With jetset, it took me all of 10 minutes to get them in and my hair was dry in 35 minutes (which for me is unheard of). You have to remember to take them out the way you put them in - don't pull them out like you would magnetics. And also don't get your hair in the very ends of the rollers or you will have breakage.
Thanks to jetset, I'm excited about rollersetting again.
