Looks expensive, but can (probably, by the looks of it) be bumped.
Also, i see a lot of spool pins, but that is something a good lockpicker can overcome.
I'd go for the chubb m3 that was mentioned before, if i were you.
Only a handfull of lockpickers in the world can pick that within a small timeframe.
Also, i'd like to advise you to not only focus on the lock.
The worlds best lock won't do much good on a door that can't take a few kicks.
My 2 cents.
Yours,
