What would be really cool is an XOR line driver, so it could be
selectable inverting or non-inverting without changing the gate delay.

Programmable slew rate would be nice too.

:-)

Thanks for the input! I think I may just stick with the Fairchilds' and
learn how to solder them well or contract the assembly. I'm getting a
bit tired of assembly anyway, and don't have time for it anymore with
all the projects that need attention.

Good day!
