The 411 ECM boxes are common around here at about $38 USD regular price and I've picked up at least one on a Half Price Sale Day. No issues with mine and a 411 is supposed to log data and live stream PIDS ever so slightly faster than the almost identical 896 ECM devices. Looks to be about the same to me.
My cold start problems were solved by a different fuel pump - bad check valve. And a new AC Delco cam shaft position sensor.
