SRID for analyzing a USA national data set in Meters

I have a data set that includes points all over the United States in lat/lng (say, SRID = 4326) but I need to do some analysis on these data in real units, say meters.  So, my task is to select an appropriate SRID that will work reasonably well for the whole USA to reproject lat/lng into meters.   There are a bazillion SRID's available. Any suggestions?

This analysis doesn't have to be super-precise, so I'm not so concerned with the limitations of a national projection (as opposed to state/region).

thanks,
Michael
