There is no such thing as an inexpensive quality red dot optic. There are red dot optics that work reliably and have good battery life and there are optics that don't work reliably and/or don't have good battery life.
Don't waste your money on cheap optics of any kind. There's no point in purchasing an optic that doesn't work when you need it to, even if the rifle it's mounted on is just for plinking. If you purchase an optic that's not up to snuff, then you'll inevitably pay for an optic that does work reliably in addition to the money wasted on the optic that did not work reliably.
Even with China's artificially low wages for skilled labor, there's no way to make a $100-$200 dollar optic equivalent to a $500-$600 dollar optic. Quality has a price tag attached to it.
Save your money and buy an optic of known quality. Aimpoint and EoTech make quality red dot optics. Get the models that permit you to use night vision if the thought even passes through your mind that you might need to use night vision. The $50-$75 extra dollars you pay for the capability is of no consequence.
I like the Aimpoint Comp M3. I think the Aimpoint Micro tube is a tad too small. I like the Aimpoint Comp M4, too, but I can put a Comp M3 and SureFire X300 on my carbine or rifle for the same weight. Basically, the little extra bit of ruggedness and AA battery are not as useful to me as the weight savings. I try to limit the weight of my added accessories to 1 pound or less.
