Thanks to everyone who responded. Those were some great recommendations and I checked out every lead.
Many options were considered including new, refurbished, used, and renting.
A used Iridium 9555 Kit from Fairbanks Satellite Phone won out at $700 including AC charger and Pelican case. Thanks Rob for the tip!
http://www.fairbankssatphone.com/Here is some of the information I discovered along the way:
The 9575 is the newest and nicest phone priced around $1,350 new, $975 used. I'm told it is a face lifted 9555 with some rubber armoring.
The 9555 replaced the 9505A (which replaced the 9505) $1,195 new, $700 used This and the 9575 are the slimmest and lightest.
The 9505A of which the USA manufactured ones seem to have a following for their durability, were discontinued last year and demand for unsold new phones has pushed the price to about $1,500, used they can be had used for about $700. There are other countries of manufacture available, such as Malaysia and Mexico but those are not considered as durable as the made in USA phones. I don't know why. Perhaps they are older? I found these for about $500 used. All the 9505's and A's are heavier and were described as being brick shaped. They have sorter battery life compared to the newer 2 models.
Lots of options between refurbished and used. Options included:
Hard sided cases such as Pelicans and Otters
Leather cases
AC chargers
DC Chargers
External antennas
Extra batteries
Data kits
Docking stations
Owners manuals
Etc.
Now for data plans. Those are maddening to understand. To keep it simple here, there are two basic types, monthly or prepaid. There are data plans for some regions, such as Canada & Alaska, or Global plans. You can buy plans for each with varying duration and minutes. If you want more info, you can go on-line and check them out. The best pricing I found for Global Plans, the only ones I considered, were at Blue Cosmo
