I had the eb854 a few years ago. It was alright but I found it hard to start, especially when it was cold in the morning. It wasn't that much more powerful than my other blowers too. I ended up selling it and getting a Redmax 8500 instead. I like that blower a lot more. If you want to go with Shindaiwa, stick to the 802. It's easier to maintain and fix if you ever need to. The 854 might be quieter and might consume less fuel but I think that's offset by the increased maintenance, greater upfront cost, and higher repair costs if and when either unit requires work.
