It's a bit too harsh statement IMO. The Muratas are not bad
for their size and for their price. I replaced mine in the
2nd RX of my MP (with a INRAD 455/2000) and measured the
params of both filters with proper matching (wound the
transformers for both sides). I started to publish the
findings on my web-site but have not finished it
completely. It is still on my to-do list and will be done
within a few weeks. 

Actually the INRADs are sharper on the side and it gives
you a difference between 2 and 4 kHz from ur RX freq on
both sides. It is just a fact of physics nothing else.
Unless you use big antennas in a crowded RF environment 
you will hardly notice the difference. But this is my
subjective opinion.
