Another vote here for the Spyderco Cat as an option for people looking for a locking version of the Urban (I think it is actually slightly cheaper than the standard Urban). I had a Cat for a couple of years and I remember carrying it as my weekend EDC more often than either the Dragonfly 2 or the Chaparral. The only reason I don't have one now is because my brother liked it so much I gifted it to him. I plan on getting another one eventually, especially now that it's being made in CTS-BD1N, which is superior to the Urban's N690Co in wear resistance, corrosion resistance, and especially toughness (the original Cat model was S30V, I believe, then it was re-launched in the budget line with a 440C blade, then later, CTS-BD1).
I still haven't seen the CTS-BD1N versions in my local brick & mortar store, though, but apparently people have been getting the newest upgraded CTS-BD1N versions from some online retailers
