I saw a lot LTO1 drives in a quick eBay search for under $300. And the
media is $30 at newegg for a 100GB native tape. I know Newegg is not
the cheapest for LTO2 media so I assume someone can get these LTO1
tapes cheaper somewhere else.

Exactly.  I have my mythtv OS on raid5 while my videos are on
independent disks. And sure if one drive goes bad I will loose about
300GB of recordings but I can live with that. At work where I need to
store medical images I have every thing that is important on raid6 and
backed up on tape at least in triplicate and some times on more than 1
type of tape drive type (LTO2 and DLT).

This is probably the easiest approach. One or two more drives could
surely help a lot.
