[Milsurplus] 1 kV Ceramic Caps- Your Choice?

[David Stinson]

Getting ready to rebuild a 50-Ohm low-pass filter board.
I need *reliablity.*  No more surplus Chinese junk.
Looking for the "good" 1st-run Chinese junk ;-).
I can buy the 1 kV ceramics from four different vendors:

TDK Corporation

Vishay BC

Panasonic Electronic

Murata Electronics

I know some like Vishay.
Anyone else have recommendations?
