Blood Pressure Machines

I recently received news that one of the men I met in Africa was very ill. I was concerned about his health so I sent an email inquiring about his health. The full time missionary in Bangui informed me he was ill but getting treatment. She also informed me it was quite fortuitous that he became ill because they also discovered he has high blood pressure. 

She told me high blood is a big problem in Bangui. The typical Bangui resident has VERY limited access to even simple medical equipment and most have a stroke before high blood pressure is diagnosed. It only costs $30 for a simple blood pressure machine. I told her how many do they need and where to send them. She put me in touch with Mike Taylor of Three Strands. His wife Myra is going to Bangui in about a week and will be able to take the machine down to Dr Mboi so he can monitor his BP. Mike is heading to Bangui in January with a large medical team. I can send an entire trunk down filled with blood pressure machines with the team. The airline charges $200 for an extra bag. I would like to send along at least 12 quality blood pressure machines in the trunk and I'm hoping to do so for under $300 for a total expenditure of $500.
