If considering a "refurbished" 2160 or 2160A be sure to find out if it was refurbished by Funai in Groveport Ohio. These should come in a sealed generic brown Magnavox box, not the red and white retail box, see the photo of my Magnavox 2160A/2160 boxes. The red and white box contained my new 2160 purchased from walmart.com and the brown boxes contained the 2160 and 2160A models refurbished by Funai (the manufacturer) in Groveport Ohio, as purchased from J&R World in New York City. Beware third party "refurbishing" operations that sell unknown goods on Amazon or other outlets that may not offer the Funai warranty. Know what you are buying!
If you purchase a 2160A be sure to check to make sure it has the latest firmware update. There have been two, or is it three firmware updates for the 2160A? Wajo has posted the latest information and links for the latest firmware upgrade.
As with my earlier AVS and MyCE advice (at MyCE as "DigaDo" in September, October and December 2009 and as "VoxHumana" in February 2010) you should start your inquiry at this gateway to the wealth of information concerning Magnavox HDD/DVD recorders:
The latest model is the 515 (with 500GB hard drive) that may be purchased new through http://www.walmart.com/ip/Magnavox-MDR515H-F7-500GB-HDD-and-DVD-R-with-Digital-Tuner/15080509
If you purchase a 513 or 515 do not use the 2160A firmware upgrade with those recorders. See Wajo's corrections to the earlier misleading information on the Funai support website.
