The Stanley 2M Series is an absolutely amazing light. It has more throw than any other pistol grip/trigger style spotlight I have ever used, and is surprisingly close to the Stanley HID. I have found it to have a very good runtime too. I have owned the Stanley 2M Series light for quite a while, and I highly recommend it.

Both the Stanley HID and Stanley 2M (both of which I own) can be run directly from their 12V DC car chargers. The Stanley HID has a standard wall-wart AC charger, and the 2M has a built-in charger that requires and extension cord, but is very convenient. Note that neither can or should ever be turned on while charging from their standard AC chargers.
I don't mean to override Patriot's excellent recommendation though; The Stanley HID upgraded to 4200K will have even more output than it does with its stock 8000K bulb, and will outperform the Stanley 2M Series light by a large margin. The Stanley HID, however, with its stock 8000K bulb, does not perform nearly as well as it would with the 4200K HID upgrade, and the Stanley 2M Series light will be the better choice if you are looking to get the performance at a lower price.
Otherwise, the one Incandescent light I recommend over the Stanley 2M Series is the Professional's Favorite 20 Million Plus candlepower spotlight $60 from Advance Auto; It is a 130W halogen light and has quite a bit more throw than even the Stanley HID. It is extremely large though, and won't be as practical as the Stanley 2M Series.

Overall, I would recommend getting the 2M Series from Wal-Mart based on what you posted. Upgrading the Stanley HID to 4200K or getting the Pro's Favorite 20MCP are still good options, though..
