So far I've mostly been picking (not a day goes by) and have burned my way thru most of the affordable padlocks and deadbolts I can get my hands on. I have no trouble with anything they sell at the big box hardware stores now, and actually think security pins make things easier. Next step is commercial high-security locks... I've recently picked up an Assa Twin, Medeco BiAxial, and a Schlage Primus (the older one, not everest), and I've been giving them dirty looks but haven't dug in yet. I'm afraid once I start with those, I won't sleep for a week.
I'm also starting to play with safe combination locks, mostly thanks to the tutorials and write-ups here. S&G 6741 is in the mail ($10 on ebay!), and I got a ridiculous bargain on a gun safe from work that we didn't have a combination for (it's a Field & Stream branded Stack-on firesafe), so I'll have those to play with in short order. Big thanks to Oldfast, Daggers, and the other spinners who have shared so much here (I actually know where to start, now) and to tumbl3r for pointing me here.
Really looking forward to getting to know you all better, learning more about the industry in general, and feeding this new addiction... it's hungry.
Thanks for having me.
