So, nobody thinks the Master Thrower prestige class is worth the levels?

I would think the ability to do a ranged touch attack would be -huge-.
The Master Thrower is worth it. The ranged touch attack ability is huge, but for the problem that a thrown weapons guy already has problems doing a lot of damage (weapon enchancements to expensive, needs Dex as well as Str, etc. etc.), and if you can't add your strength bonus to damage as well, you are looking at touch attack doing a few points of damage on average.
In the following built that I made for a one-shot game I tried to circumvent the problem by taking high damage high critical weapons (chatka's) and using a non-strength bonus (Int bonus from the Swashbuckler class) to circumvent the problem:

Trip Shot (Ex): A master thrower with this ability may use a thrown weapon against an opponent farther than 5 feet away. The character makes a normal attack against the opponent with a thrown weapon. If the attack succeeds, in addition to doing damage as normal, the master thrower makes a Dexterity check with a +4 bonus opposed by the opponent’s Dexterity check or Strength check (which ever ability score has the higher modifier). Other modifiers may apply to this opposed check. If the master thrower wins the opposed check, the opponent is tripped. The benefit of this ability doesn’t stack with the benefit of the Improved Trip feat.
Close Quarters Ranged Combat (Ex): A character who knows this stunt doesn’t provoke an attack of opportunity when using an exotic ranged weapon.
Deadeye Shot (Ex): The critical multiplier for the chatka increases by one (x2 becomes x3) when this ability is used. The benefit of this ability does not stack with any other effect that increases critical multipliers.
Weak Spot (Ex): A master thrower can gain this ability only after reaching 5th level. When using a thrown weapon against a target of her size or larger, the character can make a ranged touch attack instead of a normal attack. If the attack hits, the master thrower does not apply her Strength bonus to the damage.
Psi-like abilities (Sp): 3/day – chameleon, know direction; 1/day – psionic displacement, metaphysical claw. Manifester level 1st, save DC 8+power level.
Leap (Ex): Thri-kreen are natural jumpers, they have a +30 racial bonus on Jump checks.
Poison (Ex): Bite, initial damage 1d6 Dex, secondary damage paralysis, DC 15. A thri-kreen produces sufficient poison for only one poisonous bite per day.
