If you want some thing that keeps you happy you have to dish out the $$$$. Cheap will get you crap!
I have a laser max inside my G17 and its top grade. It doesn't interfere with regular holsters because it's internal and doesn’t alter the geometry of the gun. For light I put a Glock light I also have a sure fire. My laser was around 300 + change but the light was not expensive (Can't remember the price).
You could go TL2 light & laser combo for about 350+ from the US. I got one on another gun and I like it very much. Surefire also makes a combo but it is a bit more money.
Take my advice, if you want to be happy with the products don’t buy cheap.
