My company is currently using Caliber v3.0 and as a result, we've found we can only use TD v6.0 (we're using 6.02). I'm heard Caliber 3.2 is available, but it would take a very, very serious reason for the current "hot" projects to upgrade.
What we do have seems to work, although we're only in a "pilot" so our actual experience is limited.
QUALITY . . . is like buying oats. If you want nice, clean, fresh oats, you must pay a fair price.
However, if you can be satisfied with oats that have already been through the horse . . . that comes a little cheaper.
