I prefer the grinding results of the Bunn over the Grindmaster. The Grindmasater seems to generate more static electricity. I also like the clean out lever of the Bunn. My Grindmaster has had a few issues that required me to replace parts on a few occasions. My two Bunn grinders have never needed anything but a good cleaning. The Grindmaster works fine and is one of the 3 lb models, which is handy, but my preference is for the Bunn.
