I have to agree if you use that many lock-picks the reward should at the very least be decent.
Why? Do you know how much stuff I have that is just sheer crap that is out in storage in my shed? Behind a nice expensive Master Lock (the brand, not the level). Anyway, if a thief ever spent the time they would have to spend to break into my shed, they would be pretty pissed off too when they find what they would find.
Besides, if you get your lockpicking up to snuff, then you would not break so many lock picks.
