He's nuts about customer service, I worked on this engine and was extremely pleased.

As an example, the 60 in this video ran ok for a flight then it started kicking during start up. We played with everything, TD said he was shipping a new ignition. Remembering some woes I had with stock DLE plugs, and with nothing to do but wait for the ignition to arrive, I threw a new NGK ICM6 plug in and it ran like a top. After discussing this with TD he replaced all the stock EME plugs and ships them with NGK now.

I would rate the quality as high, and the value when stacked against other engines in its class as extremely high.
