currently i've been running a sabertooth signature series for the last 5 years about now an I still love this grinder from day one! i just bought a kannastor v2 and i think its junk! it squeeks and the lid you have to snap shut to get on. never had that issue with sabers airplane grade aluminum but sadly it seems you cant buy any of these puppies new anywhere!! what are your guy's favorite grinder you have used so far?
