Well along with RamJet in the Gulf you can add Hadid, UAS (ex Hadid guys), Jetex (ex Hadid VP), CJS and of course the traditional folks UV, Jepp, Jet Avtn etc etc.
Also the Indian folks have coverage also, CBAS, Trans Asian etc
A wonderous group, they all seem to make a living and spend heavily on media addvertising. In the past I have used all apart from Jetex & CJS, I'm happy with the folks I've used and am loyal to a few.
Good luck with your choice, and remeber you can switch at any time
