Sorry I didn't see your post before!
I'm trying to make the same decision, myself. I milled my own wheat for years before my dx last fall, but rice is a whole other ballgame. I did mill some rice in my mill (Whispermill - basically the same as the Wondermill) before I gave it away, just to see what the texture was like, but I'm still not sure what to say about it. I haven't gotten any Authentic Foods flour, yet, so I couldn't compare it to that. And I couldn't bake w/it because it would have been thoroughly contaminated by all the wheat flour in the mill. Looked pretty good to me, but it's so hard to say.
I did "talk" with a dealer whose kids have celiac, and was disappointed to hear that she does sometimes sift her home-milled rice flour. That didn't sound good. I don't remember seeing and "hard bits," as she put it, in the flour I milled, but I may have just missed them.
She did say that she thought the Nutrimill would give a marginally finer flour than the Wondermill, in any case. And I also think you can get a coarser grind w/the Nutrimill if you want it, which I know from my years w/ the Whispermill is quite impossible with that one. I did side-by-side comparisons of flour milled at the finest and then at the coarsest setting, and couldn't detect any difference.
So if I can get hooked up with a natural foods buying club again, I will probably get a Nutrimill. Buying grains in bulk works well for me, and in that case the price is a fraction of the cost of store-bough gluten-free flours. I do find that I prefer millet and sorghum to rice flour in many things, so the rice will be less of an issue for me.
Wish I had more definitive answers for you, but hope this helps a little.

p.s. I had the KA mill, too, but agree that the flour was too coarse, and you couldn't do much at a time w/o burning out the mixer motor. Also, are you able to get brown rice flour at the Asian stores? I'm still getting up to speed with all this.

I am considering buying a grain mill like a Wondermill or a Nutramill. But I am hesitant because I really like using fine flours from the Asian stores. I am worried that these mills will not grind the rice to a fine enough texture. But I have to go out of town to buy Asian flours, and the risk of CC always worries me.
So, does anyone have one of these mills, and how well does it work? I want to know how fine it really gets the rice flour. I don't like grainy rice flour at all. I used to have a KitchenAid Grain mill to go on my KA mixer, but it wasn't fine enough so I sold it on Ebay.
Anyone know about these machines?? Or do you know of another one that is good??
Thanks!
