lets assume for the sake of argument that high end locks are in fact being busted all the time. they are not, but fine. you have some broken locks in your shop that you sawed off for customers, so you see some broken locks laying around and assume thieves got them.

if it is in fact true that top end locks are being broken, then doesnt that mean the expense of your fancy key authorization locks is even more wasted, given that keys are not the weak point, and power tools will pretty much break anything?

again, my argument is that all you need to know about locks can be learned here:

and then you purchase some top brand locks like kryptonite or onguard at your LBS. your locksmith shop would not require a visit, unless you like to waste money on lock duplication protection which is totally irrelevant. those sort of locks might be great for homes or garages, i dunno. but bikes are ok with bike locks.

i appreciate your input and all, but i think your links to 120 dollar padlocks are bad advice, especially when paired with your advice about pairing them with cables as a secondary defense. then the money spent on the padlock would be a total waste, a 100 dollar loss.
