I've used tumblers for cartridge reloading and had decent luck. I've seen stainless media tumblers that do amazing. The reason I chose Evaporust is that it doesn't eat the steel, just the rust, so it can be used on more sensitive items. I had some wrist pins that had just the slightest amount of surface rust, they were NOS from a 1970 Datsun 2000, and the Evaporust took it off without any abrasion. Maybe its a snake oil and I'll have regrets down the road, but from most all the reviews I've read it seems to be a great item. It's very easy to toss small parts in and just let it soak, they won't get eaten away if they are left too long. Once the rust is gone, that's it.
I am still interested in other solutions for small parts, so keep the info coming!
