I had posted this question in a different forum but since there wasn't much response I thought I'd try here as well. I was interested in a Mantis tiller but saw the Stihl MM55 Yard Boss cultivator next to the Mantis in a local store. The Stihl is only about $30 more but it looks like it's a lot more rugged as well as better designed and manufactured. It's also a 27cc rather than a 22cc engine, and Stihl's excellent reputation seems like a strong plus as well. Anyone have any experience with both? I'd appreciate any comments you could provide.
