I know there are a number of excellent mills for different applications, so I hope I get this detailed enough to really pinpoint which will work best for me. Thanks in advance for your advice!

I'm looking for a mill that can accomplish the following;

can mill coarse or very fine flours (dry grains) for baking, pasta, hot cereal, pastries, gravies, cakes, breads, etc.

does not heat the flour (over 120 farenheit)

can sift the milled flour to make white cake flours (meaning that it's capable of not crushing the outer layer into the flour making it too difficult to sift out to get a white flour)

can mill for a large family (meaning does not heat up or mess up with heavy use)

does not need to be cleaned

does not throw flour dust everywhere

has electrical and hand mill capability

lasts for 30 years+

does not need to be babysat (won't catch on fire or break with a distracted operator)

does not have quarks with getting odd sized or shaped grains stuck and cracks, or constantly needing to be taken apart to fix

low maintenance

less than $1000

can be purchased in or shipped to the U.S. without incredible waits, fees, or bribes, and with the knowledge that defective or damaged products will be fully replaced in a timely manner without uneccesary inconvenience

Any thoughts?
