I do just fine with a vibration cleaner and walnut shell media (easily available and cheap where I live) though corn cob media works as well. A little polish in the media helps shine up the brass. If you pop the primers out first it also tends to clean out the primer pockets, though not as well as the steel pin method. (I pretty much never do this myself.) A dryer sheet in the media attracts a fair amount of crud and helps keep the polishing media clean. Other people may have methods that they prefer but this works for me and has done so for a lot of years.
I am looking for suggestions for an entry level case cleaning set up. Machine and media
Mostly 38spl and 45 LC.

...i've heard that substrate for reptile cages can be used as media.
I've tried em all over the last 50+ years ... Kitty litter , pet bedding , Rice , sand blasting media , liquid cleaners , water with pins ... and this is what works best ...
it works best because it is the proper size media and has the proper polish in the proper amount .
Get a big bowl Vibrating unit , get one twice as large as you think you will need and get a good quality unit ... I have one from Thumblers Tumblers and one from Frankford Arsenal (Midway USA brand) and in both I use the Treated Shell Polishing Media from Midway USA , whatever they call their Midway brand . Get a large bag of the media and when it stops polishing ... change the media . This media is not dusty and needs no additives .
Adding car wax to reptile bedding is not a great idea . Most add too much and make the mix too wet... it has to be dry and flow smoothly and pet bedding / lizard litter isn't the right size for case polishing ... trust me ! .
Go with the Midway Media ...a much better product .

I still use the Lyman vibratory cleaner that I bought over 3 decades ago. Crushed corn cob media, maybe just a little bit of a polish like NuFinish or Brasso, plus a used clothes dryer fabric softener sheet to trap some of the fine dust. Seems to work well, cases come out clean and ready for de-priming.
