Going a different route. Purchased this tumbler a year ago and have used it to clean ~15k pieces of brass so far.
Upgrades include improved knobs from Rockler, painted interior of drum (to prevent rusting) and the addition of a rear motor bracket.
All upgrades that are being discussed in the stainless tumbling thread found HERE
Included with the tumbler will be:
5 pounds of Pellets LLC brand XL stainless tumbling media (measured at 0.062" instead of the original 0.041" that will get lodged in the flash holes)
a bottle of lemi-shine (I may even throw in my personal "scoop" for this part)
a small bottle of the preferred original Dawn dish soap (blue of course!)
The tumblers are currently on back order for who knows how long.. I have this one IN HAND and it's set up and ready to clean the hell out of some brass!
$260 shipped and insured.. the media alone cost $50
