It seems different clinics have different success rates. One I found posted an 80% success rate w/donor eggs. The one I go to said 70%. Another RE I consulted with said 60%.
My biggest fear is, even with greatly increased chance of success, the DE cycle might not work. We plan to do one in the next couple of months and already found a donor. She is an independent donor, and I have no way of verifying if her previous cycles were as great as she claims.
