After reading many reviews on all types of grinders like this one, I decided to stick with this brand. Ryobi isn't the leader in their tools, but I'm not the best handyman, so that price combined with the work makes it perfect for me. I just put together my first set of cabinets and have used this grinder in a number of ways to get the finished product. Runs smoothly and grinds well. It's heavy so I wouldn't buy it for your grandma unless she's healthy.
