Chris If you need to buy new for some reason, I suggest that you take a look at the offerings of Telewave in San Jose Calif.. They make a full line of duplexers and they are very good and reasonably priced and they offer a ham discount. So long as you are working with corporate money, I would suggest that you spring for a 6 section unit----it will cost you about 0.7 dB in the receiver and transmitter paths which in practical terms is negligible and you will be well away from any problems with desense.
