For those that might be interested the Williams FP Legend is back in stock at Williams and are being sent to vendors

Even though it shows it with Target Knobs - I do not believe they will be on the model they ship.
Amazon says they have them also - but at that price they they very well could have Target knobs. The picture they are showing is not really a Legend but they have the correct Williams part number
