I've seen a lot of MiniCircuits BNC 10.7 MHz BPFs used in equipment 
racks over the years as a sort of "get rid of trash" filter (at least 
I'm sure that's what the person who bought them thought).  Not so hot in 
terms of phase vs temperature (elliptic filter, 2 MHz wide, centered at 
10.7), but probably pretty good at knocking down harmonics and such.

BBP-10.7+ ... $41 each.

Interestingly, only 26 dB rejection at 20 MHz. Must be in the middle of 
the first "bounce" of the response..
