I bought a first generation Nitty Gritty back in the late '70s. It's a very effective machine, but rather noisy and messy in operation. It still works, although I only use it on the rare occasion that I need to play a dirty used record.
I bought a Klaudio US machine about 7 years ago, and it does pretty much everything I need of a record cleaner. It washes, it dries, and it does it with one-button convenience. It is amazingly effective and so easy to use that there's just no excuse for ever playing an unclean record.
Most new records are not truly clean, btw, and there's no way to get the best from an LP if you're relying solely on dry brushes to remove dust.
Whatever you choose, I think the best record cleaning protocol is the one you'll actually follow.
