A cheap lock will not deter a determined thief.
Hell, it wouldn't even deter me if I needed to remove your motor for some reason, as I usually have bolt cutters in my truck.
You need a high quality case hardened lock that is hard to get bolt cutters on.
I've found that disc types are generally harder to get at with a bolt cutter.
