I ordered a couple books as christmas presents two years ago. The quality of the binding was excellent, but I wasn't as impressed with the prints themselves. I'd say they had about a 120 linescreen--better than newspaper quality but not quite magazine quality. The color fidelity was great, and the layouts themselves are very nice, with full bleeds, the whole nine yards. The recipients were VERY happy with them, but perhaps they're not as picky as I am (they are both in their eighties!).
IIRC the pages are not double sided, which is good because, say, a ten-page book would look rather skimpy, with only five sheets of paper.
