Printing books with Aperture - any other recommendations?

Hey gang!
I have used Aperture's book printing a few times for gifts for customers. I like how easy it is to use and formats easy to change. My question is are their easier/cheaper that are better quality?

Has anyone been happy with Blurb? I think the quality is better the aperture way but I this is a guess. Any thoughts.

dont know if u ever came to a decision but i found this the other day:
Mike Franklin - his blog compares apple/blurb/MPIX/MyPub​lisher/viovio

he also has indepth photos comparing them all on his flickr account - check the sets nearer the bottom

seems he prefers apple's service and quality, i agree when looking at all the pictures he's posted

hope this helps
