The Blichmann BeerGun (v1 -- I'm sure v2 is fine but it's not the same).
It does exactly what it is supposed to. It's better than the "pro" tools, despite being marketed to homebrewers. It always reliably fills bottles, to a consistent fill, with quick and easy pre- and post-purge with CO2.
Moreover, the engineering is beautiful. Every part has a purpose. Everything that could be a stock part is. Each custom part is machined as simply as can be.

Just a joy to use.
