Well my expensive chinese made RCBS Sidewinder now leaks when using a wet media. There is no fixing it apparently as there are no parts and no replacement drums. There's no warranty either since they don't make them anymore. I bet it'll be a while before I buy anything with RCBS name on it. There went $450.00. Anyway, if you are using the stainless pins or just a wet media, what tumbler have you had good results and long life. There's a slug of them out there now. My brother has the Thumblers Tumbler but he doesn't wet tumble, walnut media only. My concern with it is the drum is metal. While powder coated, my brother's is missing a lot of paint and I imagine if he did use our current concoction of vinegar and a detergent, the vinegar is going to cause rust real quick. So I probably need to stick with a plastic drum and hopefully not expensive to replace. So what do you use and do you like it?
