I only separate my plastic stuff. Even tubing, if you go with silicone, can be adequately sanitized with boiling water.
So it's basically just a plastic spoon, one fermentor (they otherwise age in glass), a bottling bucket, and an auto-siphon (though I have a few SS racking canes that I'm still looking for the best way to use.) But 4 pieces of equipment really isn't bad, and is a tiny investment for that peace of mind.
