Can't disagree with anything that's been said so far. I've had my KA for 14years now. Been thinking of upgrading to the 6qt though. Some of the things we do here like pizza dough, the 5qt is just too small. Don't get me wrong though the 5qt is very adequate for the home it's just that I'd prefer to get the whole batchs of dough in the bowl and not just half.
By the way.....You may not be preparing bread at the moment but you can't say that you won't wish to try it in the future. If you're going to invest the money in a mixer, maybe upgrading to the 5 or 6qt stand mixer may not be a bad idea. Better than having to go out and get a second mixer in a couple years.
