I haven't used them before, but I've seen people generally be happy with the Createspace offer, although formatting is apparently annoying. I think the guys offering a hardcover are new this year.
Yeah, the hardcover off is really appealing to me, as I think it would look nicer. Of course, I may just use all three deals if I decide to do any, that way I don't feel any regret at missing out on a good one. I'm just paranoid that there's some catch in store.
