I just ordered a Carden Cuda and am looking for an engine. It is designed for the DA 50. Is that the way to go? I am looking for reliability and ease of use not the most power. I have heard good comments about the DA 50, but some folks seems to have issues. I guess my second pick would be 3W.

Any input would be appreciated, getting into gaint scale is expensive and I want to do it right the first time.
