Ian, thanks for the excellent summary.   That could be a classic RadCom or 
QST article on its own!

I think it's worth mentioning that operation of PC-based VNA devices is not 
as intimidating as it may first seem.  The simple OSL auto-cal routine does 
much of the heavy thinking and set-up.  In speaking with other ops, many 
seem to stick within their comfort zone of a broadband detecting device, the 
"Type 1" SWR analyzer you cite.  If curiosity ends with SWR, then I suppose 
there's no need to consider a VNA.  But, after running a few VNA sweeps, an 
entirely new world opens up with even minimal knowledge and skill.
