Since I am in the market for a new flivver I am also weighing the different options. Edge Performance seems to be a better option if one wants power with light weight. It is an expensive engine also,and warranty might be something a buyer would have to consider.

Although a lot heavier, the Titan has more power, and $10K +/- less. Unfortunately it needs Avgas if that is an issue. You can get a car gas compatible motor with less HP though.
