There is a lot of BS around brands with hand grinders, but all the good ones are machined from a big chunk of aluminum and use the same replaceable stainless burrs whether they cost $30 or $200. Here are the differences I've found:
1. The fancy ones that let you dial in grind size from the outside usually don't work very well. They lose zero the instant you disassemble them once for cleaning, and the contraption that holds the burr in can wobble. (The 1zpresso probably works better and is more convenient, but it also costs $170+ vs. $30 for a no-name with the same burrs.)
2. The grinding handle WILL break off the cap over time, unless you buy the ones with the obviously stainless handle. (Or unless you only grind really dark roasts that crumble easily.) The stainless handles will probably break eventually, but they last a lot longer.
3. Most of these hand grinders come with a 5-core burr, but for espresso you want the 6-core or 7-core burr, which not all of them come with. The 6-core is fine for espresso, but it's worth getting the 7-core if you want to make Turkish coffee.
4. The ones that have 12 indents for grind size around the circle can sometimes leave you in-between, where one is too coarse and the other too fine to get that perfect 20-second extraction time. A few of them have 24-30 indents, but they're harder to find.
5. With some grinders you can only replace the inner burr. With some you can replace both the outer and inner burr. If you can see a seam line around the grinder, about the thickness of the outer burr above the grind container, it probably unscrews with a pipe wrench and you can replace the outer burr. Or the retaining ring around the adjuster will have screws, and you can remove them and get the outer burr out that way.
The hand grinders that cost $70-200 aren't any better than the ones that cost $30-40. The moving parts are all the same and they probably come out of the same factory. The above points are what's important, in my experience.
