My Mom has a SunBeam stand mixer - it is probably 30 years old now. It is a nice unit, but she doesn't use it much because it is heavy and she keeps it in the bottom cabinet ... too heavy for her to lift to countertop to use it.
I had the 5 qt., tilt top KitchenAid. It was a touch small for some of my recipes so DH bought me a 7qt. lift bowl style KA. I love it. I have a grinder, a shredder, a pasta roller and the ice cream maker attachments for it. The newer grinder attachment is a piece of junk, I am scrounging it for parts to keep my old grinder attachment going, lol. The rest of the attachments are great.
