I use a Thumler one and it is the best type of cleaner by far. Better then the vibro cleaner with corncob/walnut shells and the sonic cleaners.
You still get the odd blocked flash hole (not a problem with sonic cleaners) and you will have to dry the cases before reloading (not a problem with vibro cleaners) but it gets them cleaner than new, both inside and out.
