I don't recommend < $50 lights if you need them to see by, because for not much more you can get very good lights.

I have a MS900 and it's been very good. You do need to treat it a bit with kid gloves - the lighthead is OK but the battery isn't waterproof, and the power cable has a tendency to fray if you aren't careful with it.

I also have a P7 flashlight, which I had started to think was the way to go over the MS unless you needed the runtime, but in the last week it's gotten the random mode change disease that seems to hit them. It's only about 6 months old and the switch is getting flaky - it'll be OK for a day or two, then it'll switch modes every time I hit a seam in the pavement. I've had it apart looking for obvious faults but haven't found the cause yet.

I still like the flashlight - a P7 is bright enough that I find medium mode enough to see by (it's far brighter on medium mode than the Blaze is on high) and in medium mode it'll probably last close to 2 hours. But the unreliability is irritating. It seems to be spotty, there are others who have had them longer without problems, and I'm sure this is just a bad connection - if I can find the source, I should be able to fix it.

GeoMan has a P7 flashlight too, MagicShine branded. It might be worth buying from them for a few bucks more than getting all the bits from DealExtreme - you'll get it fast and they will stand behind it better than DX will.
