I've read a bunch on here about different mixers and how the newer Kitchenaid mixers compare poorly to the old Hobart made ones.

My question is; what is the difference between some of the five quart, lift bowl models?  There is a "Commercial 5" that costs $545, a "Professional 5" that costs $420 and a "Pro 500" that costs $350.  They all look about the same to me and the specs and description on the Kitchenaid website don't really explain the differences.

There are just two of us so I don't really have a need to make more than about two pounds of dough at a time.  I like all the attachments I could get for the Kitchenaid.  The guarantee looks good.

I don't guess I really need any kind, I've been doing ok by hand.  Just want one. : )
