Cuisinart is a hit or miss with their products. I have had their stick blender for a while and it's pretty much junk. Not at all near the professional level that I really need.The best food processor for nut butter will depend on your exact needs, but I believe the greatest value lies in the Cuisinart DFP-14BCNY 14-Cup.
It works well, has a good warranty, and doesn’t dance about on your worktop when in use! Small touches such as the retractable cord and accessory box also show thought and care has gone into it’s manufacturing. Plus, it’s from a name you can trust too.
