I've was in a similar situation a few weeks back. Trying to find the "final" city bike to grow old with. I eventually ended up purchasing a retrovelo classic paul-it's absolutely fantastic-but certainly expensive. It's deff something your want to put a lot of thought into and make sure that it would be the last city bicycle that you would possibly want for that kind of cash. -Contact me, if you want the name to a good dealer who has a somewhat cheaper price.-
On the point of the pashley, I've heard very good things about them, but not much my style. They look very similar to the workcycles/azur bikes-except for the guvnor-which I like the most of the line up (however this is more of a sporty ride rather then an upright city utility). Not sure how the construction is in terms of lugs and components used....
