the only thing i wish is that they didnt make them a pain to unlock the buyable versions lol
the smithing station has been around awhile and is only 1 lead, so it is easy to dig up 3, and the provisioning station while it requires 10 leads only need to be done once each for all the codex entries
the enchanting and woodworking stations though have 3 leads, with 3 codex entries each and not all of them are from "common" things that you usually do, not to mention the fairly low drop rates for the leads themselves makes it fairly annoying to try to get to the point you can actually buy the station
