I'd like to offer my opinion as someone who LOATHES the SaaS model. The first and only thing you need to consider is who you're selling to (power systems engineering businesses, as you said) and what they do. They make power systems that need to be reliable and last for fifty years or more. You probably know banks use 30 year old COBOL software to make the world tick. Why?
