I bought it at PleasantMills which has the best price.
Let me take some of their description:
The Electrolux Magic Mill DLX Assistent has been a Swedish secret for over 50 years. An exceptionally strong dough mixer, the Electrolux DLX has an impeccable reputation for long term reliability and quality results whether you're mixing a cake, whipping a meringue, or baking ten loaves of fresh, light, scrumptious bread.
The Magic Mill DLX Assistent mixer creates smooth, silky, elastic dough quicklyand easily with its unique roller and scraper design. This method effectively mimics kneading by hand, minus the time and effort. As the stainless bowl revolves, the deeply fluted roller of the Magic Mill DLX acts as your fingers, with the scraper mimicking the palm of your hand.
The Magic Mill scraper folds the dough with a rhythmic motion while the roller provides a powerful massaging action. Dough comes out smooth and elastic, in large or small batches. Any speed from 40 to 140 RPM can be selected, and an electronic speed sensor automatically adjusts motor torque to the load. A timer is standard equipment, so the Magic Mill DLX will do its work while you do other tasks, stopping when you want it to. The control panel is angled for comfortable use, and the large timer and speed controls are attractive and easy to read.
The large 8 quart stainless steel bowl of the Magic Mill holds up to 28 cups of flour (7 lbs.), to make approximately 15 lbs. of bread dough (7-10 loaves). The efficient, high-torque 600 watt motor runs smoothly and quietly; coupled with an advanced transmission design, it providing ample power to mix and knead even the largest batch of heavy bread dough without straining. The Magic Mill was given its nickname, "The Workhorse Mixer" not by its manufacturer Electrolux, but by users who praise this powerful kitchen helper that's so enjoyable to use.
So far I agree with this description. I did a large batch of dough today and couldn't figure out whether I was supposed to use the roller or hook, but I made 12 batards where my old KA could only do 6. Its interesting that this machine moves the bowl, not the attachment. Makes sense to me - one big honkin' gear to do the job. Here's some more from their site:
The Magic Mill's whisk beater bowl (the white bowl in illustration above) will create beautiful meringues, beating up to 18 egg whites (or as few as one) with excellent results. You can also cream butter, margarine and shortening with sugar to the creamiest texture for all your cookie needs.
When white bowl is used, it is stationary (unlike the stainless bowl, which turns during use), and the whisks drive from below via a center column in the bowl (the white bowl is shaped something like a bunt cake.) This arrangement provides total access to the top of the Magic Mill bowl, with no overhead motor drive in the way. The beater bowl is sold separately by Magic Mill, but we include it with your mixer at no additional charge. When mixing with either this bowl or the stainless bowl, the only metal in contact with your food is food-grade stainless steel.
The Magic Mill DLX mixer measures 13.5"H x 10.5"W x 15.7"D, weighs only 19 lbs. with stainless bowl. It sits firmly on solid rubber feet, and will not walk on the countertop during use. The entire motor enclosure is made of metal, and is available in your choice of four attractive finishes. The Electrolux Magic Mill DLX mixer has a 3 year manufacturer's warranty on the power unit, 1 year on other parts.
The biggest difference between dense, heavy baked goods and the delightfully textured products you want to enjoy is proper development of the gluten in the dough. The Magic Mill kitchen mixer is unexcelled in its ability to turn out fantastic dough. With the array of available accessories displayed below, it offers to add a myriad of exciting dimensions to your cooking experience. The Magic Mill DLX is a lifetime investment.
I started to max out my bowl with a double batch of butter cream, but I survived. I'll continue reporting on what I think of this and if its worth the investment.
