The rotary tumbler are noisy, but a lot less expensive . Reloaders that tumble a lot of brass also use vibratory tumblers.
The cheap ones do not have timers generally. Harbor Freight and eplay are good places to start.
When I reloaded, I had the vibrating tumbler. I could load around 400 or more .45 ACP brass into it, and I just fire it off. I used mostly walnut shell media as I found stuff like corn cob to not be aggressive enough to do the job.
