System agnostic psionic PrC's?

[Athetos]

Hello, so i'm in a campaign with a base in d20 modern/future, and our GM told us that we can take PrC's from other d20 based systems with a little monetary investment.

So the question is: what PrC to take?

I have 3 levels in Strong Hero:

With improved meele smash(+2 damage)


And 1 level in Battle Mind:

With the Burst(+10ft. movement as free action), and Resistance(+1 all saves, immediate)

Planning to take the Dark tempest:

Any other suggestions?

The Psiologist from Dark Sun is basically the psionic version of the Incantatrix, very powerful prc.
