Does anyone know where I can obtain the old-style, tapered single-shot basket for a millennium (51mm) la Pavoni? Not the pod-compatible one with the lip that is currently supplied with new machines, but the earlier one that had smoother, tapered sides. It's the one on the left in the picture here: Basket for Pavoni Millennium single shots.

I know there was some discussion of this back in 2012 (Too Much Coffee with La Pavoni? and Source for non-Pavoni 51-ish mm millennium baskets?), but none of the sources identified in those posts seem to still sell the old-style baskets.
