I just looked at my KitchenAid and mine's right between the two.
I mostly use mine for much smaller amounts than even 48 ounces, since I use the machine to do the chopping/working, and can add extra liquids in another container, or do multiple batches the way I might with a food processor.
Are there specific recipes you're thinking of that would require a larger container?
I love my Cuisinart. I've had it for years and it is powerful and makes great smoothies. It chops ice like a dream. . The Cuisinart SPB-7CH looks like mine, and it is on sale for $49.99 at Macy's right now.
