There tends to be a correlation between quality, longevity, and price. It's not a perfect fit but it's definitely a thing that exists.
I built a brand new cutting edge PC for a family member in 2011. They wanted to change careers and get into IT and figured they needed the bestest fastest PC they could afford. Anyway, it worked great until they decided it was time for a new one in 2019. I got to keep the 2011 PC in exchange for some assistance with selecting components for the new build. I put in a shiny new SDD, ebayed 16GB of old RAM that was the fastest thing the motherboard could handle, and I'm still using it as my primary server / workstation / web browser / cloud backup automation controller / etc. It cost more upfront but the amount of time that 2 different people have not spent with fucking around building new PCs has more than offset that in my opinion.
So this PC is on its 3rd round of HDDs and 2nd round of RAM but that was only to boost performance, not because of a hardware failure. I haven't lost a power supply, motherboard cap, fan motor, or USB port on it yet. That's pretty remarkable for a 14 year old machine that's been running 24/7. The 2019 build hasn't had a hiccup in almost 6 years now either.
Had mine done almost 18 years ago and absolutely 0 regrets. One eye went from 20/200 to better than 20/20. The other wasn't as bad and was corrected to be 20/15. Vision has not regressed at all in either eye. Dryness was mild at first but completely recovered after several months. I've had no halos or night vision problems. The most important thing to remember is that not all procedures are equal, and not all clinics are either. Go to a few different eye doctors and ask who is the best in town, and then go there. Don't get quotes, don't shop for coupons, and don't go with the 2nd lowest bidder. If you can't afford what the best surgeons in town are charging, then you don't do it. I had to save for 4 years to pay for mine (I think it came out to around $5000 but I can't remember for sure anymore). The next most important thing is to follow every instruction and post-op care recommendation they give you to the letter. I wore those sleep goggles, stayed out of the pool, and avoided touching my eyes for 2x longer than they recommended.
Granted, my research on this is all 18 years old but this was not a brand new procedure even back then. I was convinced that the vast majority of horror stories came from people who did not go to good clinics or did not follow post-op care instructions. If you remove them from the dataset the procedure looks a whole lot less risky than what the naysayers in this thread would have you believe.
