Opinions on EGO's stick edger?

I'm in the market for a stick edger and thought about getting an Echo PE-225 sgain, which I had an edger or two back. However, the EGO stick edger has caught my eye. It's more expensive than the Echo gas edger, but it comes with a power head, so I can add attachments in the future if I want to go that route. What's holding me back are power concerns. Some reviewers write that the blade needs to be spinning before engaging the grass/soil for the most efficient edging. I was wondering if any of you have used this EGO edger, especially with St Augustine grass, and what your thoughts are.
