This 5kg eBay special is $120 with the 20% discount and comes with 1kg of steel pins. I think the pins would probably clean the primer pockets better than ball bearings, which I can't see getting into tight places.

SwxJlaoH95For those interested, I've got a Lyman ultrasonic cleaner clone (identical to the one below) that I bought for about $160 and it does the job OK, but doesn't get right into the primer pockets (which I've been cleaning with a Dremel and small brass wire brush). Nor does it really clean the insides of the cases. It's also touchy about where the brass sits in the tank: if it's not right over the ultrasonic cleaning mechanism, it takes a long time to clean, so you have to constantly stir your brass around the tank to get everything evenly clean.
It has a heating element, and is fast, but it doesn't get your brass as sparkly clean as the rotary tumbled brass I've seen. I use hot water, dish detergent and vinegar. I think for all the added work I'm better off with a rotary tumbler (even if the tumbler takes an hour or more, at least it's hands-off).
