I have a lot of brand new "Sinclair" mobile duplexers available. They work great for repeaters 50 watts or less.
These duplexers TUNE EASILY on any ham/gmrs/commercial frequency. They are specified for 450-470mhz, but of course will tune down to the ham-band without trouble. I use several of these on my REPEATERS on GMRS and 70CM Ham, they work GREAT. These are some of the BEST duplexers I have ever come across. The tuning screws are easy to adjust, without coming loose, and they are built very well.
They are $200/each, and shipping is $5.00 to any US state inside the 48 cont.

440 MHz Duplexer
I am an Anglican Bishop and I travel back and forth to Kenya. My call there is 5Z4BS. I am a member of the Amateur Radio Society of Kenya. We have just been given space on a 150' tower for a repeater antenna. Along with it is not only electrical power, but also a broadband internet connection so we can do an Echolink or IRLP connection. This is big news for us since there are fewer than a dozen hams in Kenya that are really active.
We are looking to put up a 440 Mhz repeater. The hardest part of the deal is getting a duplexer--they are simply not available in Africa. I wonder if you still have one. Could you email me a best price if you do?

It could be shipped to my place in Texas and I can take it over when I go back on one of my trips.
Looking forward to hearing from you.
