Quick Characters? GURPS?
I found those two ideas to be conceptually far, far apart when I first started looking into various methods of building GURPS characters. Slogging through the character creation process, crunching numbers, tweaking and revising until you arrive at a finished product is part of the fun, right?
No?
For those that prefer to speed along their character creation, might I suggest the guidance of the GURPS guru known as The Mook.
His site is a treasure trove of GURPS goodness. More Powerful Quick-Start Characters
Check out the GURPS Templates approach to character building. You can start with GURPS 4th Edition Basic Set - Characters pg. 258.This provides examples to use as a basis for characters of all types.
For more options in a modern setting, I recommend reviewing the various Action! series booklets that really dig into the essentials of creating a character in the modern world. Here: http://www.sjgames.com/gurps/books/action/
