Glad that u also like it! Frankly, I hardly have the skills + time to build plastic models with such finishing quality on my own, and thus I switched to buy die cast or this kind of assembled models for quite many years already!
Sorry that I don't have enough "experience points" to PM yet, but the place is actually the famous model shop located at the corner right beside Wing On Department Store in Jordan (only one such shop around Wing On, very easy to find).
And the price in TD's unique language is "2 fishes" plus #*
The shop still had 3~4 boxes of T-90 with different markings when I bought mine on Father's Day, good luck!
The same brand also has a nice demo of a Soviet multiple rocket launcher on a tank chassis (TOC-1?) along with the T-90 inside the shop, but the shop owner said that he doesn't have any stock on hand for that one & expect the new stock would come in later in July or so....
