In 2009, I made a Haggadah using various sources from the Internet, with a religious Zionist theme. Since then a couple of thousand people have downloaded it and many used it for their sedarim.
It is suitable for printing. (I suppose it might work well on an iPad, but I don't recommend using it as an e-book for the seder. Especially around the wine.)
Every year I think I'm going to edit it and make it into a real Haggadah for purchase, and every year I'm too busy. Or lazy.
So you can still use it for free!
It is available here.
