Lightsheer v. Aurora - what to ask?

After years of considering laser hair removal, I finally have set up a few consultations and will be making a decision next week. Hairfacts and Hairtell has armed me with a load of questions, but I am not certain what I should be considering with regard to the differences/similarities between the Lightsheer and Aurora - the models at the places I will be checking out.

Any advice or insights? I am interested in knowing your expereinces with the two models as well as things I should be considering while at the consultations.

THANKS!

Also, FYI, I have fair skin and black hair - will first be considering have bikini and upper leg done.
