I have used Dunestar 600's for decades without issue however I am in the
process of changing to individual VA6AM band pass filters at the antenna
inputs. I will only need one filter per band and no filter switching is
necessary. I have the filters, I just need to make coax cables and move my
antenna relay into the shack. Pavel makes excellent custom filters and he is
a super guy to do business with.

I use ICE 419B band pass filters between my transceivers and amplifiers. 
  They work, but I realize that others may work better.  To my knowledge, 
these are the players in the low power (200 watt) automatic band pass 

New prices listed
$318 ICE 419B
$505 Dunestar Multi Band Remote Switched Bandpass Filter
$700 DX Engineering 419 Automatic Band Pass Filter Systems
$700 AS-419 - "BandPasser II"

Are there other systems out there?

What is your experience with each of these?

How would you rank them?

Has anyone modified and published a "how-to" to modify the ICE system 
for better performance?
