Question about cheap torque wrenches for engine mounts

I bought a $40 torque wrench online for a Cessna 172 engine mount job, and it was off by 15 foot-pounds when I checked it with a calibrated tool. That's a $200 re-inspection fee and half a day wasted. Anyone have a brand they trust for critical fasteners?

Used to cheap out until a similar thing happened to me.

Switched to a used Snap-on from a pawn shop after my cheap one failed a calibration check. It was about a hundred bucks and holds its setting. I check it against a beam-type wrench before any critical job now, just for peace of mind.
