I've found the best starters are the ones made by Meziere. They use a motor that's smaller in diameter and a bit longer than the motors other gear reduction starters use. I replaced a Powermaster with the Meziere and immediately noticed it spun my motor over significantly faster than the Powermaster, which was supposedly a "high RPM" starter. Unfortunately, it's probably the most expensive starter too but in this case, you do get what you pay for.
