I've had much success with the CM-7000 (WhiteBar repaired mine, too) and the Zinwell ZAT-970A. I've got two of each (the Zinwells are in storage as backups for the CM-7000s. However, one of my 5000s has been dead for about a year, so that unit is no longer in use. I've actually used either 5000 since before that; I'm purely on WMC (with ShowAnalyzer to skip commercials) and 5TB of storage for HD content.
So, I'll likely be putting my units up for sale soon.
