I prefer the G400s over the MX518 as I like the more grippy shell.

You can get cable replacement kits for the MX518/G400/G400s for $9 from eBay that includes new feet and a USB cable. So I'm really not worried about longevity.

P.S. You should take the mouse apart and clean it probably at least once per year. I cleaned my MX518 after about 5 years when the scroll stopped working consistently. I was shocked how much hair was on the inside, blocking the scroll sensor.

Yep. I just bought a new USB cable for mine myself, and switched to a spare I had.

I find I need to clean my scroll wheel maybe twice a year. It gets more stuck with gunk over time, and it becomes harder and harder to scroll.
