I remember when I was in R' Willig's shiur he quoted a number of things from the hagadda of the Nesivos, מעשה ניסים. He highly recommended it. I bought it and was not disappointed. It has a lot of very nice explanations of the hagadda. If you are looking for a new hagadda with a perush in hebrew to use this year, I highly recommend it. When I bought it many years ago it was a softcover, I assume that it still in print and available.
