Matrix Orbital is popular with the PC case modding
crowd and has a wide variety of serial LCDs in the
$50+ range:

Scott Edwards has been selling serial interface LCDs &
accessories for more than 10 years. $49 for a 2x16
serial LCD w/ backlight:

Crystalfonz has them for less than $40:

None of these options would require anything more than
a power/data header on the main board.
