It looks like the majority say repair my TARA LABS APOLLO cables. I think most feel there isn't much of difference in sound between cables?
No, thyname has it right. You cannot go by what "most" say because odds are "most" don't know what they're talking about.
You are probably better off to repair. But not because there aren't differences between cables. There are huge obvious differences between cables. Some of them are worth every penny, and then some.
The reason you should repair is because that is the right way to do it. Never buy anything like this. Fix what you have- it is so freaking cheap and easy. Then start learning about cables. Do not ask people for recommendations. I never once in years here asked anyone to recommend anything. Why would I do that? I would be just as confused as you are now. Consider recommendations as nothing more than suggesting which stuff you might want to learn more about.
Instead, read reviews and look for user comments. When you find cables with reviews and user comments that reflect what you are looking for, and the price is right, that's your cable. That's my approach with everything, and I keep doing it for one simple reason: it works!
