I had pretty much decided on the Artisan ($239 on Amazon for cobalt blue), when I noticed a larger, more powerful (but lift bowl) on Amazon for $249. It's not the "Professional"--it's the "Deluxe" edition. Motor is 450 Watt (as opposed to 325 for the Artisan) and the bowl is 6 quarts, rather than 5. Anyone have experience with the deluxe edition? Seems like it's worth it for $10 more, but would love to get some opinions. TIA.
