Counter top mixer recommendation
I have a 22-year old Kitchen Aid Ultra Power (I think the bowl might be 5 quarts?) that is still going strong, but it's too small! I need one that has a larger capacity and a strong motor to mix dense cookie dough and knead bagel dough.
I am considering a Kitchen Aid Professional series but have my eye on a commercial Kitchen Aid from a restaurant supply store. The commercial mixer is expensive compared to the Professional but its main attraction is it appears to be more rugged. Professional models are on sale all the time and can be had for a reasonable price.
What are people's experiences with the Professional model? Are there other brands or models I should consider? I will live with this new mixer for decades so need to purchase wisely.
