I really like my OFNA starter box. It makes a sometimes harder job of starting an RC engine very easy. It all depends on what you can afford. If and when you ever buy one....you'll wonder why it took you so long to get one.
I'm waiting for the day when all we'll have to do "while sitting in a lounge chair" is point a remote starter "like a TV remote" at our engines and push a button and the engine fires right up. May be closer than we think!
