Fiber Optic Scope Recommendations

[1FZj80]

Some idiot solicitor pushed my doorbell switch and wire into outside wall stud-bay
It's been driving me crazy because I can't hear when someone knocks on the door. Missed a few deliveries because of this.
I don't really want to bust into the stucco and was thinking of buying a scope to find the wire and fish it out of the wall. Any recommendations? I don't want to spend a ton, but also don't want a POS.

$20 eBay dental camera. Looks like an EPT test in the photos. Can be whittled down a bit to fit in spark plug holes. Requires using a laptop as a view screen. Has 6 LEDs for light.
