Eagletac are made in China, no?
SRP is abrasive, it has cut, don't be putting that on reflectors!
I have loads, nearly 30 lights, I have some $20 lights and some $300 lights.
In my experience it is all in the QC. Some of the cheap lights are DOA and need threads cleaning, o-rings lubing/replacing, maybe even a solder joint or two touched up but that's all, once you are over that all of mine are super reliable. I actually quite enjoy getting a new DealExtreme jobbie and having to work on it before putting it into use.
I think given the saving and the slightly novelty nature of the lights, buying cheap, tweaking and using for a while before putting into 'service' is good way to go.
