Here's the outcome of the NewEgg Sceptre monitor deal. NewEgg, after many emails and finally a direct contact through the real-time messaging, gave me two RMAs for the monitors.

This was probably the best of all worlds, because I was not terribly impressed with the quality control of Sceptre.
In the next day or so, Office Depot put Acer monitors -- 22" widescreen LCD panels -- for sale, for the same price as those Sceptre's (after rebate; means extra sales tax but no shipping).
Ran a burn in on the new Acer monitors and they performed flawlessly.
System is all set up and working wonderfully (after some trial and tribulation getting Firefox installed.

Now have a Shuttle to reconfigure for somebody as yet unspecified.
