Best Blenders For Dates?

Im currently on a bit of a health buzz and am trying to use dates in a lot more of my baking instead of sugar. Alot of the recipes I am trying to follow want me to blend my dates into a paste. This process seems to take forever and today my Blender actually started smoking. I currently blend the bigger pieces with my nutri bullet blender then blitz with my sunbeam stick blender. The motor on this gets really hot as well. So what I want to know is there a better blender out there? Or maybe a better process? TIA
