There arnt a lot of iridium
handsets to choose from , mainly The Motoroal 9500 ( obselete), 9505,9505A and the latest 9555. The later the better. But I go a secondhand 9500 on ebay a few years ago ( with loads of extras) for 200 dollars. But I think the various wars recently have dried up the secondhand market. All the 9000 series are good performers, with the latest units being more robust and offering things like two way SMS etc
Other then that its off to a satphone dealer on the net.
