Imagine buying a brand new 2013 vehicle with a no-lemon warranty and finding out your replacement is a used 2010 model. According to DTV this is ok.
You're comparing apples to oranges there.
DTV policy is plain scum.
Who's is better?
If I have an HR24 that dies I shouldn't have to accept anything less than an HR24 replacement. If they don't have any refurbished ones then too bad - replacement will be new. That's the fair and honest policy people expect.
HR24's get replaced with HR24's. That's been well documented on dbstalk.com.
