Anyone know where (if) I can purchase 58mm SSP burrs for my Mazzer Mini (vintage)?

Thanks in advance!

SSP lists 58 mm burrs http://www.espressotool.com/shop_view/?idx=3 It looks like they are $195 when they are available.

While SSP makes some of the burrs that people are talking about, there are many burr cuts and sizes. Not all taste the same. In commercial settings, the attraction of SSP burrs is often their coatings that can increase burr life. I'm not sure what your expectations are for your Mazzer Mini or if the SSP burrs for it would get you there.
