To keep people like me out for a while buy a Medeco. Pins not only need to be at the right height, but also the right rotation. They are a real pain in the ass to pick. I don't even know any locksmiths that can pick them. Good security for the money.
Bosnian Bill and LPL... Okay they can pick them, but they are like the 0.0001% in skill.
Still even then pay an extra $100 for really high quality disk detainer lock like a Protec 2 and you will keep even them out for quite a while.
That is what I use on my luggage. TSA has to call me to unlock them with my consent every time. The way I like it. Great tip I picked up from Deviant Ollam.
