This is the one we own, the peanut butter plus option is newer and something I don't have... But will soon enough.
http://countrylivinggrainmills.comAmerican made, and versatile as it can be used to grind bean flour, corn flour or wheat flour, and apparently peanut butter! Spendy yes, but in comparison to the cheap Chinese crap that's out there it's worth the money. I did a good bit of research before I bout mine. Looked at electric and manual. And this one won out because it is manual but can be adapted to be driven by an electric motor or a bicycle with a little ingenuity and a a v-belt. One thing about manual vs electric is temperature. Electric ones make the wheat hotter which supposedly kills some of the nutrients, don't understand that to be honest but that's what my research found.
Grinding with this one in comparison to the cheapie a seemed to be that it was easier because of the quality of the product and the size of the wheel and length of handle that it uses. I can attest to its ease of use but cannot personally provide comparisons as this is the only one I have. I have also done flour in the vita mix though. Temperature also seems to affect the effectiveness of milling, so cooler is better, or so it seems.
