You can also get refurbished on certain parts. Fixing up wheels yourself may be beyond your capacity, but you can find performance wheels refurbished at a bike shop for deep discounts, and they will be good as new so long as you don't intend to treat them rough.
It's not beyond my capacity so much as I only just got a truing stand a couple months ago but that rear rim is definitely toasted after it got tacod. It's a significant reason to why most of my miles are on the trainer.
There is no way you could treat them worse than most athletes, after all.
Especially seeing as I'm pretty sure my FTP doesn't break 200 xD Never ridden with power or done any testing though so *shrug*
Most ebike systems are quite easy on the wheels.
