I am currently running version 3.789. I'm currently working on making a stealth kit (will post pics when complete) and was wondering if I should upgrade before I tuck it away (so to speak). I've been holding off since it's actually working quite well for me. I've read the positive and negative reports of the latest firmware and was hoping that a yet a newer revision would come out soon. So I'm having a tough time deciding if I should stay status quo or upgrade. Thoughts?
