I've made up my mind that a hand grinder best fits my single dosing work stream. I've settled on an HG-1 and am currently on LWW's wait list. I have seen several used one come up for sale... any where from the 2012 version through 2017 (LWW says the 2017 is what they are currently shipping). I know there are some basic differences in ability to make adjustments across the version, early models were stepless and had an option for smaller burrs, reference dots or numbers on the burr colar, TiN burrs versus non, etc. Buying used would be preferred, given the break-in time and a (slight) cost savings... but don't come up that often and are snapped up quick when they do.
For those that know and have used the HG-1, is there a "best" version to look for? Or just take it that each version had slight improvements and shoot for a 2017? Or maybe put a different way... is there a version to pass on given issues, etc?
