I have celiac disease, which is essentially an allergy to wheat protein, and I've been GF for 5 years now. (Why does that sound like I'm at an AA meeting?) When I first started baking all my own breads, cakes, etc., from scratch, the books said that I needed a bread machine. I bought one and it didn't work so well with the GF "funny flours." A book finally told me to forget about the machine, buy a stand mixer and use the oven. Brilliant!
I bought my Kitchenaid and haven't looked back. I use this thing at least twice a week, sometimes every day. I don't know how I lived without it. My mom just bought one after she saw me calmly measuring stuff and dumping it in while the mixer mixed all by it itself. (She's been suffering with a handheld all these years.) Stand mixers also mix more thoroughly than handhelds. They also can mix chocolate chip cookie dough all the way to the end of the flour additions.
I've had my Kitchenaid for about 5 years now, though 3 moves, and it's still as sturdy and reliable as the day I bought it. The paint is still perfect. Not a scratch. Certainly not a chip. It's beautiful and lustrous. I have Onyx Black. While I like the look of the Onyx a lot, it's obvious if there's a little flour dusting the top of it. This makes it convenient to clean, but if you don't use it very often but do want it out, you might want to choose a lighter color that won't show dust.
Caveat: It's heavy. B/c I use mine so much, I display it on my counter, drag it forward, use it, wipe it off with a damp rag, and push it back. (And wash the bowl, of course.) But it's worth it's weight in gold. They are a lovely appliance. Not like a frumpy toaster.
Also, a previous review somewhere said that it left dry ingredients in the bottom of the bowl and didn't incorporate them. There's an adjustment screw that you have to fine-tune before you use it. Instructions are in the booklet. I adjusted mine before I used it for the first time (I compulsively read instructions,) and never had that problem.
Buy yourself a proper mixer. You'll be so glad you did.
