catch228,
If you foresee getting into the modding thing, get something that can be modded.
If you have an L4, get a KL1 head. You can mod the KL1 with a highdome luxeon. You can do this yourself, if you have basic soldering skills. If not, there are CPFers that could do it for you. You could also add a low profile fraen optic and have it overdriven to 700mA.
The modded KL1 head would be interchangeable with the KL4 on your L4 body. Although the KL1 would be a 1 watter and it would not have the total light output of the KL4, it would definitely out throw the KL4 by a long shot.
Another option in an incandescent (did I spell that right?) would be the Pelican M6. Many people are modding these with really good results. The parts needed can be acquired at the Sandwiche Shoppe. If you're not comfortable doing your own mods, the drop modules, commonly know as McModules can be purchased already completed on this forum. The PM6 costs about the same as the Scorpion, but you get a holster with it. Check out batterystation.com. They have 'em for $30. Use this link. It's a special CPF link.
