Do you have a link for one? Because all the ones I’ve seen were a lot higher than that.

That is only $99 bucks and will kill any fox or smaller animal.
That link has gas-piston barrel-breaker air rifles in all prices but you can get a dandy for less than $200.
I got a Hatsan Edge Vortex 22 cal a couple years ago and have killed over 100+ raccoon, opossum, and skunks for $100 and it is still going strong.
In my opinion you are better off getting one with a gas piston instead of spring piston, they last longer.
You only cock it once for each shot and they are WAY MORE powerful than the old pump-up pellet rifles.
Most popular priced crossbows will have a hand-crank option for about $100 more.
I think barnett makes a hand-crank crossbow that shoots 370 fps for about $450.
If you look around you can get one for about $100 less than that.
