Most members would agree that the Perlicks are worth the extra money because they are forward sealing faucets. This prevents the faucet from sticking when you have not had a pour for a while. Because of this advice, I splurged and bought the Perlicks the first time. I have read many different posts where the writer suggested to get the Perlicks from the beginning.
I wish I could say more, but my first kegs are conditioning now and I have yet to try out the Perlicks. I hope that this helps. Mark
