I have done this with an old HP workstation monitor.  The monitor originally
had 3 BNC connectors on the back (RGB), but you could order a sync board
for the monitor which would give you H-Sync and V-Sync inputs (this board
was about $39).  I then purchased a VGA->5 BNC cable ($40) to hook it up.

The major problem with this setup is that many (all?) of the older workstation
monitors are fixed frequency monitors.  This means they can only be used
at the resolution they were designed for (1024x768 in my case).  They work
well if you're running Xfree86 in graphics mode, but they are unable to
do 80x25 text mode (you just get garbage on the screen).
