amen, on both counts.

i had one problem i feel like sharing, b/c is cost me a drive head.
a tape snapped while loaded, so the tape leader (~1.5 foot strip of
plastic that grabs the tape end of the tape when loaded and drags it
through past the head and around the spindle) and some amount of tape
where left in the drive.  you have to take the cover off and run the
leader back through its path.

if you ever have to do this, DO NOT insert the leader vertically past
the head.  guide it past the head horizontally along the path and tape
"rollers", doing your best to keep it away from the face of the head.

dropping it through vertically is definitely the easiest, but buggers
the head.  the manual that came with mine said nothing about this, nor
did the pdf i grabbed off quantum's site.
