@ WeAretheUnion –
I assume you have experienced the prop by SpookyProps. There is a significant difference between this produce and the cheap Gemmy or other consumer type product. My experience was that they are very life like, minus the exhaust.
What does an electric offer? Most of the noise comes from the chain rotating on the bar. If you pull that off what is left to offer a chainsaw effect?
The problem I was struggling with was the $750 price tag for the SpookyProps product.
