Spigots (and valves) on fermenters scare the heck out of me. Once you take your first sample, there's beer residue up in there growing all manner of nasties, and you can't properly disassemble and clean it out until you've emptied out all the beer -- through the contaminated spigot. They're fine on a bottling bucket, because you start clean, and bottle the whole lot in one operation through the clean spigot.
