Personally, I'm a huge fan of the ME Crafting Terminal. I consider it superior in every way to a Fabricator because it doesn't accidentally craft two dozen of something you really only wanted one of. Or craft a few dozen something else completely different that was the partial recipe for what you were actually trying to craft (iron doors instead of iron blocks, for example).
For hands-off autocrafting, there's the Cyclic Assembler. They can be hooked up to craft in sequence, just like Fabricators do, but don't craft anything until you tell them to.
I'm pretty sure we need to nerf KingLemming.
Whovian, Whovian where are you?
