Honestly, are you having that much trouble finding a grinder to fit your needs on the INTERNET? try ALT, GC, EDIT or ebay.. the brand really dosnt make a difference try space case, cosmic case, mendo mulcher, etc.
I can't find you the 3.5'' XXL grinder... just buy one of these. Sharpstone herb grinder 4 piece with screen - Official Source-
ALT is aqua lab technologies . com GC is grass city, EDIT is grasscity, these are all online headshops
