Globalsecurity.org is decent the other ones seem OK to me.
Confirming whether or not Syria actually has the Iskander-E is difficult.
A report by Haim Rosenberg, a former Israeli defense official, said the Iskander-E rocket, known in the West as SS-26, would mark a significant improvement of most Middle East militaries.
Syria, the UAE, Malaysia, India and some other countries have shown an interest in the missile system," said Rosoboronexport official Nikolai Dimidyuk. Russia will also seek to export the Iskander-E to Algeria, Kuwait, Singapore, Vietnam, and South Korea, he added.
Some things may seem a bit suspect but that's as good as your going to get with this stuff, make up your own mind.
To me it's clear Syria have shown an interest in this weapon and Russia are willing to sell an export version, the only question is have they taken delivery yet, I'd say they probably have.
