I bought a Bosch AXT 1600 quiet shredder several years ago after many rave reviews in this group. It's had a lot of use and now the helical cutter is getting blunt and has a few nicks, which may be why it's started to jam more. Maybe I'm too impatient and shred stuff that's too green, but I'm sure it used to cope when new. I guess it would be pretty difficult to sharpen the cutter.
Anyway I had planned to replace it with an AXT 2200 that uses cogs rather than the mincer mechanism, but now I see there's an AXT25D that's more powerful yet cheaper than the 2200. Anyone have one yet?
