The first year I did them, I had them done at
http://www.sbtoshare.com/. They turned out well, but they were not two sided. I heard last year that they will do a special order both sides if you request it. I'm thinking of trying that this year. And what I also did that year was have ONE printed at SB2Share and then had the rest photocopied and bound at Office Depot. They all turned out well.
