I grew up with a shop built circle mill, Oklahoma style. I learned the operations from my grandfather, and still learned something new oftne about technique and method.
I bought a big Meadows #1 many years back and got with the program, and the difference between a "Belsaw style" circle mill and the real deal that was built for production sawing was night and day. And what I discovered was how expensive circle milling is...just the fuel for 100 horses to turn a 60 inch blade is measured in multiple five gallon cans a day. The teeth and shanks were not cheap, sharpening is done on the blade and is a learned skill. Don't get it right, and the blade can do amazing things, plus overheat and cup, wobble, and you think it may come right out of the husk. The log turner is nice, but not really needed on a bandmill.
I then bought a Mr. Sawmill with electric power. And it is the cheapest mill to run. If I sawed a lot, and bought a sharpener, it would be pennies to run instead of twenties. Plus, you theoretically have more boards due to the thinner kerf of a band, plus you have less chance to hurt yourself or anyone else.
