Most of European factories that do 100 or 200 copies, cost pretty much the same. It's up to choose who you want to work with. If one has exceptionally brutal artwork, then one may look into pressing only discs, and doing the booklets somewhere where it won't cause hassle. For example, whether the pressing plant cares personally, there may be laws in some european countries that make it unnecessary risk for them to press small pressing of filthy noise with questionable symbols or other such things.
Most places are brokers anyway, and do not actually own the CD pressingplant themselves. Some of them may do disc at factory and packaging elsewhere and might be flexible and all sorts of obscene nudity may not be issue.
I have said it before, but I think major point of publishing obscene releases is not where it is "easy and cheap". People who do not want to put the effort or money into project, because it might be slightly difficult or costly, should not do such releases. Making exceptional releases comes with the price.
