The only time you'll really need your electric starter is when you leave it home. The only time you'll cut your finger on the prop is when you're hand is wet with fuel. The only time you hand start an engine is when you forgot how much it hurts and costs when a backfire bites you good. I've watched my old man in my youth who never owned an electric starter, hand start all engines of all sizes and that's how I started out. But over 40, the healing process takes a long time. I'm just not ready to patch up a deep cut over a hobby. My old man got most of his scars from tuning, that is most, but not all. I like to go home relaxed. No electric starter will turn a gas motor that I'm aware of, so a welders glove goes with me for those and I smack it over without a thought. the smaller engines usually are the fussy ones in some cases. I typically use an electric starter in the morning, and then hand start it warm after that if I'm feeling alert. After 33 years of starting engines, I've only been bite once, by a .051 TeeDee engine. I can handle that. Today, flying .40 and .60 sized planes, I don't want to think about the risk of an emergency room visit to look macho. $20 for an electric starter is a lot cheaper than a first aid kit.
