Query: Fired for lack of performance

I'm finally deciding to replace this mixer. I have owned it for years (and if you think that is a GOOD thing, read on ...), but I have always been disappointed in its mixing power from Day 1. A month ago, I had an opportunity to use my mother-in-law's hand mixer from the 1970s, and was amazed at its power, even on the lower settings. That made me decide to give my current KitchenAid Ultra Power hand mixer the heave-ho. It is SO wimpy, and there is very little difference between the 5 speed settings. I think mine has lasted so long because not much is required of the motor. Certainly, it can handle cake batter just fine, but that's not all I demand from a mixer. I like knowing a mixer has extra power even if I don't need to use it very often. Not sure yet what I will buy as a replacement, but I wish I could go back to the 70s and purchase the mixer my mother-in-law has (and maybe say no to that disco dress I bought).
