Or, how about just looking for a used "off brand" mixer like a Thunderbird? Thunderbird mixers are very good mixers, but because they are an "off" brand (everyone looks for Hobart) they can be had a lot cheaper. A couple of years ago I saw a brand new 80-quart Thunderbird mixer, still bolted to the delivery pallet, with hook, flat beater, and 80-quart bowl sell for $2,200.00. There are some 120 volt 40-quart mixers out there too, and I would advise you to stay away from them unless all you plan on mixing is pizza sauce. These mixers will require either 208 or 220 volts. And don't forget about the Hobart VCM (vertical cutter mixer). This is also an excellent mixer that is well suited to mixing dough but is typically off the radar screen so prices can be pretty reasonable when you find one.
