Hi Szimi I can only give feedback from the Apple book Have done several and have no complaints Only had on image which did not match the one submitted and maybe I did something funny with the color space?
Do take your time for the layout and will come up with a winner !!!
I have seen several books from blurb.com and they have all been quite nice. Helped a friend put one together and we are both quite pleased. It needs just a little tweaking before we order more. Easy to use software with several nice templates and really good customer support. From everything I've read, they're about the best out there -- claims are that the printers they are using deliver a better product than both IBook and lulu.com. I'll be doing several for myself as soon as I can find the computer time. Give them a looksee.
Another vote for blurb.com. I've printed several and my wife sometimes uses them for a low cost wedding/portrait book for customers. Book pics are right on as long as you have a calibrated monitor. Layout software is pretty easy to use. My only complaint is that the hardcover books only come with a jacket, rather than images/text printed right on the cover. After a while, the jackets will start to show some wear.
I know this is a little late, but it might help someone who comes along. The PhotoWalPro blog is running a series on book printing comparing several different options. I think it is a once a week thing, but shouldn't be too hard to find.
