There is one point you should know. I bought my Celestron telescope from USA through a friend of mine. However when I was assembling it, I noticed the label "MADE IN CHINA"

. So if you have a friend there, you can do the same.
It is that Asians have no interest in selling things to Asians. They always aim America and Europe.
Regarding what you said about PC accessory sellers in Sri Lanka... I agree 100%...very true. But Sri Lanka is the best place to live in this world.
One thing I really must tell you.... having a telescope by my own was one of my dreams from childhood. However, I was only able to touch it for couple of times since I wasn't able to do much with it. Now I have almost no interest to waste time looking at stars as there are plenty of things to learn over the internet

.
So my advice is to find one and experiment with it before buying it.
