$150 Robotic Vision System
But for the fact that this is designed for Arduino, I'm pretty impressed with this package. $150 gets you a full RoboRealm license, nice camera, pan & tilt servos, laser module, hardware, uC, driver boards & power supply. That's quite a deal:

At first blush the Propeller Servo Controller USB should fit the bill. Add a Pitsco or Lynxmotion XY bracket pair, some servos, and a basic USB cam at least equivalent to the Livecam, and you'd be out around $95. You'd have to get the RoboRealm license separately.
Don't think Trossen includes the laser module on this one.
