I had a good lock on my college bike. The thieve stole parts off my bike. Fortunately for me, it was a x-mart bike and I was not too upset. That was about 20 years ago too.
I suspect a ugly paint frame might prevent theft. I recall Sheldon Brown did this with some old frame years ago, paint it with a brush stroke any time he could.
