Aagh, should read 54mm!!
£20 only, including postage.
They are between £30 and £40 new depending on where you look. Mine’s little used and I think £20, which will include postage, is a fair price. These are adjustable with regard to the depth the press inside the portafilter and, personally, I found that I could level and not bother tamping and that gave me a consistent puck with no channelling.
