Anyone know where I can get cross needle meters, with one volts and the other

you might need to make a new face plate for the SWR style meter.

I don't know what your application is (maybe you're looking for traditional d'arsonval meters), but these days, a microprocessor driving a LCD matrix display might be easier. If you can deal with bargraph or numeric displays, a $30 arduino would probably do the trick.. 10 bit ADC inputs are standard.
