I just ordered one of these this morning and was wondering how many folks are using them. I do intend to order some of the pins for it but the kits were out of stock at Sinclair's so I just ordered the unit itself. I had one like 25 years ago and sold it along with other reloading gear after a divorce and now getting my gear back in order. Before ordering the pins I like to try some walnut media in it and see how it works over the vibrating units and was wondering if others tried it or just stuck with the SS pins.
