Try calling hi-volts in Islamabad and see what models they have and for what price. They have home delivery but after payment through a bank. Or If you or someone you know is coming from Islamabad, ask them to bring the model you want. And try calling v-sel if they'd take your order. Last time when I did(a couple of years ago) they didn't. Btw do note that there is a lot of difference between a GSR and an SR. One obviously about quality but they other being playability. GSR has smaller fret spacing and good for really small hands(downside being slapping etc is harder, lowest strings are relatively loose etc) and SR having larger fret spacing, good for normal/medium sized hands(and less of the downs mentioned for the former.). Similarly Yamahas have larger string spacing which give it a different playing feel. So which ever one you get, they all have very different feel to them and If you like any one of these, you are likely to not like the others.
The prices in UAE for everything are inherently expensive. So, check out the prices there and compare with the local prices. If the difference is not much, I'd suggest getting local because of convenience(and warranty; Although it is not really needed as long as you treat your instrument well.) In Dubai, there is this, "Fish Round about" in deira. There are a lot of music/audio shops there for almost every thing. Although there are a few shops with selected brands in the big malls of dubai but you can most of the stuff around fish round about.
