You can never go wrong by choosing the best brand.
There are several brands in the market available today. These blender brands are top of the line, and probably the most expensive one. However, these are known to be solid, and worth the money. Especially if you are going to make shakes and smoothies, or protein mixed drinks often. These drinks necessitate crushing hard ice to give them that extra special taste and texture.
If you are going to crush the beans, the heavy-duty blender will not have any problem with multiple uses. You can also use a portable shaker blender to chop nuts for garnish or to add cooking. If you are going to use a blender to mainly make purees or juices and to not destroy much ice, you may be able to settle for a cheaper brand that is also very suitable for this purpose.
While a cheaper blender will crush ice, nuts, and coffee beans, remember not to overdo it just in case. Pay attention to how hard your blender is having to work to complete these tasks.
Do not buy a second-hand blender
If you can avoid buying a blender that is used, you should. Used blenders can last a long time, but you never know how much wear and tear it has on it, or how it was stored and taken care of. Your blender will be a well-used appliance so getting a new one gives you the advantage of being able to exchange it if you are not completely happy with it. However, if you are sure that the second-hand blender has not been used often, then it will probably be a good buy, and you can learn whether or not you want to upgrade to a new one in the near future.
