d20 Mentalism

As some of you may know, I prefer the d20 Modern/Future rules for my version and vision of SF.  However, I don't like the psionics presented there.  I use the Psychic's Handbook by Green Ronin.  It replaces powers a la spells with powers as skills.  The system is pretty easy, and much like Star Wars' Force powers; make a skill check to use a power.  Using a power causes fatigue, which is tracked against you hit points, but can't kill you.  Its a simple, useful system that works well and doesn't make it seem like spellcasting.
