John,

The ICE filters are fairly inexpensive ($35) and very small. I have a
number of them I use to minimize inter station interference at field day.
They sell both a wide and narrow version for 6m. These filters are only
rated at around 200 watts and I have heard tell of failures on the HF
models. You can order them from www.arraysolutions.com

The other option is a filter from DCI. These are larger and MUCH higher
priced. They likely have slightly lower losses and better out of band
attenuation. These are also low power models too. I have a DCI filter
for 440MHz and it is an amazing piece of equipment. I used to use it
on a 70cm FM radio here at home. My antenna is about 1/2 mile east of
a commercial paging antenna. With the squelch full up and the preamp
in the radio disabled I had almost constant squawks breaking squelch!
With the filter in place and the preamp on I set squelch at the ragged
edge and have NEVER heard a squawk! I have never noticed any attenuation
issues with the filter unless I try to listen to public service (which
I can't hear at all!).
