I like the idea of spray painting the antlers orange, great idea, state land or private. Or if you don't want to permanently paint your deer at all, get an orange vest, like a dog vest, and put it on your decoy. Any orange fabric you could drape on the body would work and shouldn't effect it's effectiveness on the deer. You can get those orange safety vests from Fleet Farm/Farm and Fleet/Menards, or whatever is in your area, for just a few bucks.
So that's the safety aspect. As for which one to go with, the primos or the carry lite you mentioned in your post, in my opinion, are equal decoys, and I would go with the better deal on your wallet. They break down and all parts fit in the body, the ears and tails both move, and the antlers can be removed to use as a doe. Those qualities, along with light weight for easy carrying, are all the main things I look for in a decoy and I think either one of those two decoys are equally good. So all being equal, I would go with the cheaper one, even if it is "only 20 bucks". I wouldn't throw a 20 out the car window, so why not save 20 bucks if you can?
How far you're carrying your decoy is a huge consideration. If you have to carry that thing a long ways, you might want to consider a fold up 3D cardboard style target. I'm all about the real looking decoys if carrying distance isn't an issue. But that decoy will get old real fast and will live in your garage all year if you have to carry it too far.
