I too use the Porter Ports, and find them to be very effective. (To be honest, I had them installed when I had my dedicated lines put in, so I don't know whether it is the ports, the dedicated lines or the combination of the two that caused my sound to improve (significantly)! I assume it was the combination of the two, and I am very happy with the results, particularly in the bass response, which is deeper and tighter.
From a value standpoint, they seem to be a pretty good value, less expensive than the PS Audio ports, but more expensive than standard non-cyroed hubble port.
As far as where to buy them: Merely type in "porter" in the search menu here on Audiogon, and they'll pop up!!!
PS Albert is a really nice guy to deal with, (and to talk to about all things audio). I hear he likes to take pictures with his old Kodak Brownie camera too! :-)
