Recomendations for a VNA
 

Hi gang,
I know there are several professional engineering types on the list,
so I thought I'd post this here. I teach at a technical college and it
is budget time. My boss asked me for a "wish list" and a vector network
analyzer came to mind. What I had in mind would be something we could
use to characterize small signal BJT and JFET circuits at say 3-30MHz.
VHF and UHF would be nice, but not required. I'd be looking for
something that could provide real and imaginary values, so as to be able
to develop s parameters for various circuits.
In order to qualify for consideration, the unit would have to be new,
and non-kit. :( I know HP and others make things like this. Any
recommendations?
BTW, I know something like this is going to run in the kilo or tens of
kilo buck range. Hey, it's their money and they asked. ;) ;) ;)

Thanks for the input.
