I have a Nebo Redline its under $24.00 on Amazon. Probably not as nice or bright as the higher end lights but still good in my book. I bought over two years ago, and have have no complaints.
You don't need to point your gun at whatever needs to be illuminated to identify the potential threat. In addition, there are very simple tactics you can use to not give away your exact location.As far as weapon mounted lights, I'm not a fan. First off it requires you to point your gun at whatever you want to illuminate. Second it can act as an aiming point for your opponent (a hand flash can be held off to the side if needed).
I agree I was thinking that the weapon mounted light would be good for a home defense option though i have plenty of light s at home one on the gun especially with a strobe feature might be nice to have.AOK said:Two is one and one is none. Get both and learn how to use both properly.
As for handheld... You don't need to spend $100's of dollars on a surefire flashlight (if you're willing and have the money more power to you, they are great lights). However, you can get a solid light such as a Streamlight ProTac 2 for around $40 or so.

It puts out 180 lumen, and it can be operated one handed. In addition, it is large enough to use as an impact weapon.
