I own both a Spark Pro and a Spark Hunter. I love my Spark Pro. As for the light, yes it isn't visible in sunlight, but honestly, I never turn the light on, inside or out, I still can see my dot.
Now, I have a 2x cross hair lens on my Hunter model. Well, I didn't care for it hunting. I had to mess with a scope cover to make sure I didn't damage the lens walking through the woods, and then had to deal with rain or snow on the lens. I got it for a pretty good deal, so I've got the lens if I ever want to use just a 2x for target. I ended up going back to an up pin without a lens for hunting, but still believe strongly in my Spark Pro.
