What are some of the best publishers for obscure out-of-print works? I've been trying a few different brands that mass-print facsimiles of out-of-copyright books, and some are better than others. I have a Forgotten Classics paperback which is alright other than a few typos, but I also have a "Scholars Select" hardcover which is just fucking awful

Are some of these "publishers" better than others? Which ones should I look for?
