Taking electronic items to Addis Ababa

Ok this is my story. I will be flying out to Addis to work at an International school next week and as i began packing my bags i began wondering whether i would be charged import taxes on some of my electronic household items when i arrive at immigration/customers. So my question is can i pack the following items in my suitcase without paying taxes on arrival:
1. DVD Video player
2. Play Station console
3. Router
4. Two laptops ( one for myself and my daughter)
5. Electric fan
6. Printer
Any way you kind of get the picture.......any advice?

Dear Raymond,
there is only one advice for you. You should contact the administration of your International School as soon as possible.
The staff there will know the latest rules and if possible, they will help you.
Good luck for your new job.
May if you like you can write an inmail to my expatblog account for any further questions. I am interested in your school.
Best regards
Thorsten
