I would add a word of caution.
Most Parallel ports on laptops (and I assume accessories like this) are probably "printer" oriented, and not fully bidirectional. I would be anxious to see if it actually works reliably with your ST8.
In addition, based on the experience of many here, USB<->RS-232 converters are a bit hit & miss.
Sounds good in theory, and $90 isn't too much to blow on a test, but I would wait until the "early adopters" have worked out the kinks before buying one ;-)
