[R-390] OT: Panel Meter Sources?

[Barry]

Does anyone know a good (read: inexpensive) source for a round Simpson panel 
meter?  I'm looking for something in the range of 0-15 to 0-30 volts DC with 
an outside diameter of 2-5/8".  I've looked all over eBay and haven't found 
exactly what I'm looking for.  There is one auction out there now (oddly in 
my hometown) with something close, but the meter is a bit larger in 
diameter.

I have a very nice Simpson 0-5 amp DC meter and want a volt meter to match 
it for a power supply I'm completing.  I know I'm being a bit picky, but 
they're going right on the front panel of the P/S so would like it to match 
if possible.

Thanks gang,
