I've been using that same tumbler for a good three years and I think that wet tumbling is great. One caveat - I do not require really shiny brass that looks factory new. My brass comes out clean but with a matte finish to them.
I do not follow the common procedure. I normally will stack up brass in a plastic colander, spray them with lube (the frankford arsenal stuff from midway), size/decap, then start the tumbling. Washes off the lube and cleans the primer pockets, so it's very efficient.
I typically get 125 .223 cases per drum or 300 9mm cases per drum. I use hot water and a couple drops of dishwashing liquid and a capful or two of concentrated lemon juice. Tumble for 30-60 minutes, drain and rinse, refill and tumble again for another hour, then rinse and dry.
I dry in a dedicated toaster oven, 150 degrees for 45 minutes and they're ready to trim and prime.
The longer you run them, the shinier the brass will be. I let one batch run for around four hours once, by mistake, and they came out looking like new brass. But as I said, I do not need my brass to look like that.
While it will be less noisy than a vibratory, it's still not exactly quiet. Also, get extra drive belts, mine break every six months or so. I run three batches (750 cases) per month.
