It looks like there's been a few TSZ07 on eBay recently, they
cost as much to buy as to ship (sub-$100 for drive).  I imagine 
they weigh three or four stone.

Stupid lazy questions: they plug into 120 VAC, or some other type of
power supply?  And what's the difference between the -CA and -AA 
variations?  Are there good Linux packages for dealing with foreign
tapes, such as handling variable block sizes?
