Espresso machines and two-way radios (Nairobi)

I am in the process of moving to Nairobi and plan to bring along an espresso machine (not the ones with cartridges - one that works with beans) as well as a set of two-way radios.
Can anybody suggest which brand(s) of each type of equipment is/are easily repaired/serviced in Nairobi? I would hate to get stuck at the first issue....
thanks a lot, Mario
