There is a writeup on Drivethrustuff called Classes of legend: The psionic knight. No preview. Anyone knows whats it like? (beyond having good BaB and poor manifesting ability, that much I can guess from the intro thingy)

I have a copy of it.

It's full base attack, with something like ranger psionic progression - no powers, etc til 4th level, and then a lot of per day class abilities.

It suffers from having quite a few dead levels (no new class features, no new powers, etc), but it isn't a horrible class. I'd personally prefer the psychic warrior's versatility.
