I'm not sure if they'd be classified as POD, but we used Print Ninja for the Outcasts of Jupiter physical books we sent to Kickstarter backers. They do offset printing for orders above 500, I think... might be 1,000.
They've got great customer service, lots of paper options and are pretty accommodating. They were also a lot cheaper than the other offset printing options we looked at, though they do ship from China, which may not be in your budget.
We wanted to avoid digital, and were really pleased with the quality of the prints we got back. Our backers loved the look of the book too.
EDIT: I see my brother, Shof already replied to this thread Oh well, now we've got pictures!
