I have a similar KA 6qt mixer (white--it was the only color years ago)--it's at least fifteen years old. The ones that are TSV here on QVC are often a lower wattage and a special model. So check the specs when it goes on sale.
If you keep shopping around, during Christmastime, they go on sale at Bed Bath and Beyond and on Amazon for around the same price or lower than the TSV's usually are, and you can choose a standard model.
If you need to judge about the 6qt--it's better for bread if you do 2 loaves at a time and it's better if you're cooking for a crowd, like doing mashed potatoes at Thanksgiving. I gave up my bread machine because the KA just does it so well. A few more steps (you rise in a bowl and form a loaf for the oven) but it's not much more work and the bread comes out amazing. I got the flex paddle to go with it recently and it's very good.
