I had to use DE+DS, so I understand how that makes dembie look attractive, but I was older and needed to move along, so hanging out on waiting lists for a long time, plus the less attractive success rates that go along with FETs made me decide to do a fresh cycle overseas.
You might want to look into Barbados.
South Africa would be an option, too, but I think it's substantially more than other overseas destinations these days.
And, of course, you can try lower cost U.S. clinics Shady Grove and CNY. I don't know how many African American donors CNY has being in Finger Lakes region of NY, but SG is next door to Washington, DC, and if they don't, it's not b/c they can't get them.
