I think it's important to point out that now you need to be conscious of your female gecko having a "rest period." This can be done by separation from the male or a cooling of the temperature. Separation from the male does not always work since some cresteds can retain sperm and she will keep laying fertile eggs. The more effective way is to cool them to (someone correct me if I'm wrong) the mid-60's range for a few months a year. This is so she has time to recoup and not lay eggs for a while, and can restore her calcium sacs. Wouldn't want your gecko laying to death (don't laugh, it's happened).
