They are very precise, and can move fast if well kept. Still, don't play unneadlessly with them, because they get noisy after so many changes. Still, they may work fine for around 10 years on an everyday use.

That was the first example I stumbled upon. Don't know how good they are though... |
There's 20 turn pots too, made with high precision for test instruments. They're not cheap. Check Mouser, Digikey or some other electronics house for listings. Sometimes you can find the parts cheaper, just make sure of manufacturer and check the datasheet.
Here's the thing about multi-turn pots: how do you keep track of how many turns you have made? A single turn pot or linear slider is so much simpler.
