I have no complaints and no dust problems with my Lyman turbo 1200. Run it with green corn cob media from Lyman as well. One container lasts me for about a year when cut 50/50 with crushed walnut lizard bedding from a pet store. That's around 3000-5000 rifle cases for me. At $20/year for media it'll take many years before I reach the cost of a stainless tumbler and stainless pins. I also don't have to bother drying my cases after tumbling. It gets the job done for me with a smaller up front investment, insignificant costs for consumables, and much less mess (no liquids, no drying, and like I said I've never noticed any dust outside of the tumbler bowl itself).
Stainless works very well and does an excellent job if you want shiny cases. Personally, I've never found shiny cases to shoot any better, the small amount of extra force to FL size cases doesn't bother me, and the claims of extended die life with stainless tumbling are unconfirmed. If old timers got 50+ years of regular use for over a hundred thousand rounds with their dies and either no tumbling or dry tumbling, I can live with that.
I'm not saying stainless wet tumbling is a waste of money. It gets your brass cleaner than any other method; I just don't see any advantage to it for my current applications.
The one thing I would like to wet tumble (or use an ultrasonic but if I'm going wet, I'd just go with stainless pins) is the 45-70 cases I use for black powder shooting. The black powder residue needs soap and water to remove before dry tumbling. For the amount I shoot (a couple hundred rounds a year for fun) I'm fine with washing by hand but if I got into it more I'd probably pickup stainless pins and a wet tumbler.
