BTW, having seen a recommendation for a cheap PCI/ISA POST card go by here on Marvin... I was wondering if anyone had ever had any experience with the high-end cards? I remember lusting after one (or more) for quite some time.

The best known manufacturer is probably Ultra-X: http://www.uxd.com/kits.shtml (and see the menu at the top).

Any other "high end" diagnostic products in your arsenal? 😉

Somewhere I have a "dream list" of a technician's tool kit (never actually affording it, sadly), and it includes products from Ultra-X.
