Under $120? Maybe you can find a used one.
I use The Kitchen Mill by Blendtec. It's electric and cost a lot more than $120.
I use it to make gluten free flour, which costs a packet if bought commercially. I can't buy rice flour ground fine enough to not be gritty, but my mill grinds it beautifully fine. Because of the cost of gluten free flour, my mill paid for itself very quickly. However, wheat flour is really cheap, so your only benefit is the much better taste when you grind your own.
I suggest that you not waste your money on any mill that will not grind fine enough with one pass. Chunky wheat flour would be pretty much unusable. If the mill won't grind fine on the first pass, it isn't going to get any better by sending the flour through again. The stones are set where they are set. They will grind so fine and no finer.
If the only thing you will ever grind is wheat, wheat is soft, small, and easy to grind, so a cheaper mill will do the job. If you ever plan to grind anything larger and tougher (like dried corn) you will need a mill with more power and stronger construction.
Your flour mill is not the place to try to save money.
