At work, we're using DAT-3, but are getting close to its limits. So I did some quick research to see what the options cost, and found out the Exabyte had done some buying.
$6K is too much for us; realistic max cost will be $2K (and $1.5K is better). I didn't find any loaders in that price range, but did find DDS-4, Exabyte Ecrix, AIT, and DLT drives. However, any new purchase is probably six months away.
