The TAC LS recyclers are great for most purposes, but when building really large stations the fact that they only service 10 Kerbals at most gets annoying. It means you need to add 30 parts to recycle oxygen and water. Are there any mods that add larger converters? Or a self-contained "all in one" recycler? I like TAC because of its realism, but for part count's sake I may be forced to use USI instead.
