A very good friend of mine is from Kenya and once the political issues settle down, Kenya might be worth checking out for a trip. They've got lots of game reserves and organized tours also. Kenya has a large tourism draw too, due to the parks and beaches in coastal areas(and is also one of the more developed East African countries).
I would not go to Kenya at the moment w/ the political issues and the recent violence b/t the parties (mostly tribal related), but once that is settled, I would not be terribly worried.
Here's a general link about travel and various regions in Kenya, if interested:
