Welcome to CPF, Vinnie!!
Since you're using your light(s) every night, a rechargeable light will save you some major bucks in the long run. The Pila GL3 is a favorite around here: built like tanks, they can use rechargeable li-ions and primary lithiums (CR123's), and they have optional LED tailcaps (for when you don't need a full blast of very bright light). Another alternative would be the Streamlight Strion. Also rechargeable (but uses a +- proprietary li-ion battery pack), small, and bright. You can buy either of these with car chargers to keep in your rig and they're small enough you can carry in your pocket or in a holster (neither has clips for pocket carry).
Some of the smaller SureFire (SF) lights are nice as well: L4 is obscenely bright and small, the L2 is slightly larger but has 2 stages (low and high), the A2 has LEDs (for low light) and a bright incandescent lamp (for lots of light). The disadvantage of these is that the rechargeable battery options are limited. You could, however, try one of SF's rechargeable lights: a Nitrolon Commander (8NX), or the aluminum version (8AX) - with chargers these may be out of your price range.
In any case, check out the "CPF Specials" thread for links to reputable dealers who offer lower prices to CPF'ers. jsburlys.com is my preferred place for Pila products, and OpticsHQ for all things SF.
I can almost promise you won't use your 3D Mag after you try these lights.
