Whilst you may get a really secure lock, how secure is the bag otherwise? If you can break the zip or put a knife through the bag the lock isn't going to help much if someone really wants to get in the bag.

Also really secure looking bag and lock could equal really nice things inside, take the bag and worry about getting in when you are in a safe place. 

Down side to ABUS, pain to open without the key, unless you have bolt cutters. Friend used 2 going to defcon, and they were cut off by the TSA. At least they left the guns in the case alone.

Heh it takes me roughly 1 minute or less to open the very small ABUS padlocks with lockpicking, and 2-5 minutes for the "Master" (brand) padlocks that costs around 20$

Those locks are generally not going to keep you secure, not even those that are "hardened" and fire proof, because most of them are barely protected against lockpicking.

Doh, down side to playing with as many locks as I do. I said ABUS, was thinking Abloy. They were $80.00 abloy locks that got cut off. anyway if you get the right ABUS, they'll be disk locks too. HArder to open.

AS for the master locks, I think they're starting to make them better.. Locks I bought 2 years ago, I can get in, in under 10 seconds. Stuff I bought last year, takes me about 1 minute. Locks I bought for Maker Faire Detroit's Lock Pick Village this year, 3 to 5 minutes each.

So we saying ABUS are the best lock to get but they come at a price

Just a note if you are traveling by air in the USA the TSA only allows you to use certain approved locks;
