Hi JoeBoy!
I own both these lights, and to cut a long story short the RQ beats the recoil hands-down.
Reasons for this are simple;
-The recoil thrower is built cheap everywhere! The material is thin, the finish looks like cr@p, o-rings are too thin. The RQ however is built like a tank! Everything is made thick, anodising is great, threads are nice, its a very good hommage to the Spear (even the lens on the RQ is 3mm thick glass, just like the spear). Do buy the exact model you posted, the other spear clones on DX and KD are no where close to this model (sucky reflector, thinner material, crappy soldering and anodising).
-The recoil thrower is a bit like an aspheric; You get loads of throw but thats it, everything that cant be turned into throw is lost in the design! The throw on the RQ is almost on par with it imho but on the RQ you also get some very nice flood! Also, the recoil will throw one of those square beams (if you can get it focused properly, mine wasn't) and i just don't like that
You can see the recoil as a wide laser and the RQ like a flashlight with a very tight beam and thats what you want!
-The heat-sinking on the recoil thrower is far from ideal. If you run the light for prolonged periods on high i think the led could suffer some damage due to heat build-up. So either dont use it on high too much or modify the light so it can sink more heat in the body (like i did) but even then there's simply not that much body to sink heat into.
-The recoil has a glass mirror and quite a thin glass lens that can both shatter when dropped.... The RQ is just a tank period!
For those $6 there's simply no discussion on which light to get.... Go RQ or go home!
