A point that is, I think, underemphasized in lock discussions is that geography plays a large role in the type of lock you need. In my large (1 mil. + population) midwestern city, most of the bike theft involves stealing a bike that is not locked at all. Decent cable locks seem to be all that's required, as I'm not aware of any thefts involving the use of tools. Consequently, the only locks available in bike stores are standard U-locks - no fahgeddaboudits, and not even any Evolutions are available.
Which is fine for my area; unfortunately, I travel with my bike and sometimes need to take a better lock than I can buy here.
