A projector is exactly what it's name says... do you remember back in grade school when teachers would use the projector in class to put stuff on the screen, its the same idea. You have a cancave peice of glass that uou shine a light through with a predetermined focal point to dictate light output and denisty at a given point. This far surpasses the normal scattered reflector housing because it doesnt have to change direction and there is no parasitic lose with the reflector versus the projector.
That being said as for options you can go after market housing that use a "projector" they are cheaply made and the output speaks that. Even that route it is only a low beam hid projector and the high is still halogen reflection. Next you have the option of building your own lights I know a few on this forum have such as jhouse, asur and muself. Where you buy the projector and hid kit and retrofit it yourself. Here is an example of my 05.
Lastly as you stated before you can go to JJ at retro shops and the money he charges is very fair the output will be far greater than the 200 after markets and look awesome as well.
