Anyone who thinks your time doesn't have an equitable value in money is fooling themselves. Money is just a conversion of time anyway. Everyone here exchanges their time for money every day. And everyone comes to a point where they believe their time is worth more than they someone can pay them. Just because you might not think of your time in relation to money, there is a price there. And because there is a price, there is a direct correlation between what you would spend and the time you save by spending it. To me, spending $100 more to save 20-50 hours of doing something I have no interest in doing is well worth it. On the other hand, if it were to save $1000, it might be a different story. Everyone has their price. Yours might be $10, but you still have a price.
Sometimes you have money and don't have time. So you spend money to save the time. It is a door that swings both ways. And whether it is worth it or not is pure opinion.
As for RGB LED's, I like them. It's a "coolness factor". Like a rotating monitor, or an interchangeable control panel. Sure, there is some value in having the buttons turn to the color that the original game used, and the more games you have, the more useful it is. Having the lights change colors while in "attract mode" is pretty cool too. When I saw that I could do that, I decided it was worth the extra $250 on top of the regular price of the controller and buttons, so I did it. I also bought aimtrack guns, which are horribly inaccurate and not very much fun after the first couple times you use them. I also bought U360's, which while they are nice sticks aren't the best for specific games, and the analog mode is all but useless to me. I also got a coin door, which is just for show even though it works. See, I spent a lot of money on things I didn't need but wanted. I didn't expect to spend $3k, and if you take out the pedals I bought, the a-pac, the Logitech g25 wheel and pedals I bought that I intended to build a cab for, and perhaps some other things like the player 3 and 4 and a couple admin buttons, maybe the wheel for the spinner, then I could dial this back to less than a grand. But so what, it was free in the end because I made it all back on the next two cabs I built. (yes, not free because I had over 200 hours of labor, but whatever, I enjoyed that time and did what I wanted to do.. I could make another $3k building a few more cabs that people are lined up to buy, but I got bored of it and have other things to do that are more worth it to me).
When it comes down to it, the money didn't mean anything to me, the time I spent didn't mean anything to me. What mattered was the smile on my kids' faces when they played, the pride I felt when I delivered the cabs to the people I built them for, and the knowledge I gained and people I met from getting involved in the hobby. Even the time spent playing games on it has little value compared to those things. Sure, there are regrets, but those other things far outweigh them.
