I'm not planning on taking the discussion offlist, though I've had a
few responses offlist, and those have recommended Ecrix or AIT, so
those are the leading contenders.
My boss is really leery of Ecrix, no matter how much I push it. She's
worried that, should something happen to the company in two years or
so (since they're the only one doing this kind of tape/drive now), we
won't have the $$ in our budget to purchase a whole new system. I
keep working on her. :)
