Which Drive Will Give Me 16x Burn and 40x or greater DAE?

I want a drive bascially like the NEC 3500 that will do 16x DVD-R and +R and will do 48x on a CD-r. The only thing that keeps me from getting it is that it only has 32X DAE. I need a higher DAE. Is there any drive that has the same specs and has a higher DAE. I never see the DAE on any specs.
