I was looking into buying a tamper for my Gaggia classic.
Through doing research this tamper seemed okay and I found it on Campos for $75 shipped, if a first time customer you can use the code for an additional 10% off, WELCOMECAMPOS10 bringing it to $67.50.
The Campos site doesn't mention which pullman tamper it is but upon researching it, it seems like it is the Pullman Coffee Tamper, Nexus Jarrah Flat 58mm.
Alternative brewing has the same tamper for $119 not inc shipping (https://alternativebrewing.com.au/product/pullman-coffee-tam...).
Still sorta expensive but some may think it's a deal.
