Theoretically, open tuners could be made to be higher quality for the same or similar cost as cheaper enclosed tuners. I can think of 2 reasons off the top of my head for this:
1 - You can make them slightly bigger, therefore more robust because they don't have to fit into an enclosure.
2 - The cost would be reduced because you don't have to make the enclosure itself (one less thing to have to make).
Haven't had too many of them, I just remember the old open gear tuners from Seagull back in the day were really nice and felt very high quality.
If dust were really any concern and one didn't want to keep the guitar in a case when not in use, that's an easy and convenient fix. Just plop a baggy over the headstock when not in use. If that's too much trouble for anyone, then you don't have guitar problems, you've got lazy problems. LOL.
