Cheers for the link! The one off ebay looks like it has quite a large curve round the tamping edge which isn't ideal. The 'sharpe edge' Torr Toys ones look great though. Maybe custom will need to be the way to go...
I'm looking for a 53.5mm tamper in the UK. Anyone know where I could find one?
It's for the IMS basket for the Sage 54mm portafilter and my current 53mm tamper is a bit too small.
