I've used the BCB filters from ICE and was satisfied with their performance
in my situation.

I have a 50 kW BC station on 1530 kHz about 1.6 miles from 
my QTH, with mostly salt water between us. The signal 
level on my 90 foot Vertical is over 20 dBm. When you 
touch a wire to the feedpoint you can see a small spark!

I find that most receivers' front-ends overload on this 
antenna but when I turn on the internal antenna tuner, the 
high-pass function of the tuner gets rid of the overload.

This may not work all the time, but is certainly a simple 
and low cost solution, if it works for you.
