Yeah, it is really tight in there, Tim. I'm sorry to hear that M&M didn't work out for you. I've still got my old one here thinking I'd have it repaired for a spare one day. I'll probably not do that now. Anyway, my PD ATS has worked flawlessly. It is pretty basic but does the job. Just have to protect the system with something.
