I just got a BD burner and 20 single layer discs for $110 at newegg
last week.  I have not installed or used it yet, but I got it to
archive my camcorder's recordings.  I'm not a big fan or archiving to
optical due to the need to swap media and the inability for reliable
incrementals..  (Back to the 2TB drive topic) - I bought 9 of the
Hitachis that Fry's has had on sale for ~$95 for 3 or 4 months, and
have had 0 issues with those.  I carved out a 4TB array that I only
mount r/w when I am backing up to it.  I do not backup A/V media, but
do have many virtual machines for work that just take too long to
re-provision, so I back them up as well as the configs from all
machines/docs, etc...
