I generally download the big files from the JPL site:

Then I run the file through a program I wrote called tlesum, which reads the TLE 
file and a file called visual.asc, which contains a list of "visual" spacecraft 
and their USSPACECOM and COSPAR identifiers.  It creates a file called visual.tle 
containing only those satellites that were in both files.  It also generates a 
summary file with inclination, apogee/perigee, etc., for the entire list of 
objects.  The whole thing is crude, but effective.

Of course, it's a subject of some debate as to what constitutes "visual" - I've 
only seen a fraction of the objects in my list.

If anyone is interested, I can upload the program and visual.asc files to the 
Oxford site.
