When it comes to "mag" style lights, there really isn't quite such a thing, other than small 10-16W customs. If you just mean an aluminum tubed HID flashlight of traditional proportions, there are a few available out there however, none of them are going to be ultimate throwers compared to the lights BVH mentioned.
24W-35W aluminum tube lights come from the traditional brands, Wolf Eyes, Microfire and AE Light.
The Wolf Eyes Boxer 24W is the smallest and takes 3 x drop in li-ion 18650 cells. All of the lights are rechargeable but with this light you don't have to purchase a battery pack from the manufacturer. You can purchase individual cells of your choice. On the down side, the regulation isn't perfectly flat (most of these lights aren't) and the beam is a rather blue 6000K
Microfire has a 35W model called the K3500R with is more powerful than the Boxer or AE lights but once again the color temperature is rather blue. It is however the smallest 35W light available. It compares in overall light output to the larger automotive based 35W spotlight such as the POB. On the down side they're a bit expensive and a little more than what you want to spend.
The AE Light, Xenide series of lights are probably the nicest of the lights mentioned and use a little better bulb than the other lights mentioned. They have the feel of a maglite on steriods and due to the larger battery packs have great run-time. They also have smooth reflectors, something which none of the other lights mentioned will have. This mean that the beam will be more narrow (less floody) but also throw further than the other lights. These don't have the warm 4200K beams like the better lights that BVH mentioned but once broken in have better color than the others previously mentioned.
The newest aluminum HIDs to the party are the Oracle and Tactical HID lights. In my opinion these have a lot going for them due to the price and warmer color temperature. The 35W light are large but also run longer than the 35W microfire. Neither of these lights have been perfect so make sure that you purchase them from a good retailer if you buy one. That way if you run into any problem you can send it back. I would lean toward these lights if you're value minded.
The ultimate lights in your price range are the N30 & L35. Don't let the pictures fool you, these lights are not big! They are compact, handy lights with far better beam than any of the previously mentioned lights. They were designed with input from light enthusiasts and a couple of CPF members played a big roll in bringing these to market. They compare well to lights costing twice their price. The L35 is a virtual feather weight because of the li-po battery that's used and is within your price range. The output will be comperable to the Stanley but will run much longer and is wrapped in a much higher quality light body with nicer overhead handle. I can't think of any reason not to buy one of these lights. N30 problems for example have been much lower than the Tactical HID and Oracle lights. As far as I know every CPF member who purchased the N30 when is first came out still has a working N30. I don't think I could safely predict the reliability over time with regards to the Tactical and Oracle.
In summery, Best Value,
Tacical HID and Oracle
Best in aluminum
Xenide25
Best overall
N30, L35
But, it would be nice to have a strong light when my wife and I take our dog for a walk in the neighborhood at night.
