Only RS on ebay.... and "local" dealer is 20 minutes away, never been. I'm having bad luck staying sharp with the RS on the 441 so wanted to go back to semi-chisel for the stuff I'm cutting right now.
All Stihl parts and wholegoods are dealer only. They spell it out pretty explicitly that the only way their stuff leaves your store is on foot. They ain't kiddin' either. It protects their dealer network which is a big part of why they are so successful. That doesn't mean its impossible to get Stihl stuff online however. You have a few options. (RM and RMC are for all intents and purposes, equal. Both are yellow-label.) Baileys - Have to call them apparently? http://www.baileysonline.com/Saw-Ch...-Chainsaw-Chain-Loop-33RMC-72-Drive-Links.axd You could try these guys: http://www.gohagan.com/pages/CustomCatalog/Product/7746 Or you could try RMC3 chain, which is green label but still very good, just not as fast in boring cuts or with the nose buried. If bar nose isn't buried, it will cut just as well as RM or RMC. You are much more likely to find RMC3 on the shelf at your dealer or online.
