I have used many mixers over the years in my kitchen but the KitchenAid Professional 600 6qt 575 Watt Stand Mixer is by far the absolute BEST that I have ever had / used!  I am an avid baker and can't live without this one.  I have had a KitchenAid stand mixer for years and recently upgraded to the professional unit for added versatility.  (The previous model - which still works perfectly - I gave to my sister and she absolutely loves that it!!) 

This model - because it is for the "professional kitchen" - is one that will handle almost any job.  It comes with a 6 quart stainless steel...
