I definately would reccomend adoramapix.com if you are looking for good quality at a good price. I have used a few different places and I like them the best by far. Their books have a thick quality paper and don't have a gutter so you can do panoramic spreads. You also have a lot more design options than most others. They also have wonderful customer service. We made one for a guestbook for our wedding. Two pages were stuck together and made a little tear. We contacted them and they just asked us to e-mail a pic of it and they sent us a new one right away.
Uh, after spending an hour and a half finding pics, uploading and arranging I realized that they arent high enough resolution. I'm going it have to do this another day.
