Exactly. Total cost for me was < $10, but I needed a disconnect, hose, and the stopper. Already had the picnic tap and bottling wand.
Still cheaper than buying the part from HF and wondering if it'll to the trick. I normally would be encouraging experimentation but in this case it seems like a lot more work for at best, the same outcome as the linked one, and at worst, a waste of money, and potentially getting things into your beer that you don't want.
