I came across an article from 2013 on the Good Housekeeping web site in which they tested five garden shredders. They gave two shredders identical top marks, the Viking GE250 and the Bosch AXT Rapid 2200, and then rather confusingly in my opinion named the far more expensive Viking GE250 their winner.
To me the Bosch AXT Rapid 2200 garden shredder would seem to be the better value machine.
As I write this the AXT Rapid 2200 seems to be widely available with retailers charging roughly similar prices.
Sellers I found were:
Previous purchasers from those sites seem to give broadly positive reviews of the Bosch AXT Rapid 2200 garden shredder on the sites.
The Bosch AXT Rapid 2200 has a blade cutting system and a cutting width of 40mm.
