I've been doing some print-on-demand pricing for an upcoming project, and I checked out the POD service now offered through OneBookshelf (Drive Thru RPG), which wasn't around the last time I needed to print a book. Turns out their prices for full-color printing blow Lulu and CreateSpace out of the water. But it's new, and I don't know whether to trust it, in terms of quality and service and whatnot. Has anyone used it? They seem to do their printing through that Lightning-something-or-other company, and I don't know anything about them either.
