I too love my Kitchenaid and have had it for about 30 years.
My friend just got one recently and she got two bowls with hers, a 4 1/2 qt and a 5 qt size. Both of her bowls have handles so being the good friend that she is, traded the 4 1/2 qt with me, so now I have one with a handle too. It makes it so much easier to hold, especially since I'm getting older and the arthritis is setting in. (this getting older is no fun)
However, one thing I did notice is that the quality of the ss bowl is not the same. My old one is much heavier than the newer one.
I did see a review recently and someone had mentioned that the head that tips back is more convenient to use, rather than the 'lift' machine (an all along I had been coveting the 'lift' style)
