It seems that the Perlick's are the hands down favorites on this board. I'm compiling my Christmas list and hoping that Santa thinks I've been nice. I'm aware of the Perlick 425, 525, and 575 options. I've seen talk of Ventmatic or Shirron that also seem to have been seat forward designs, but are no longer available. The remaining option seems to be the standard faucet we've seen our whole lives.
If I understand things correctly, my current options are the Perlicks and the standards. Please let me know if I'm missing something or have something incorrect.
