I hope this is not considered hi-jacking...

Yes, one can find 7/64 at ukhammocks, dd and on ebay. But when you want to go to thicker ropes, like 1/8 or 5/32, its difficult to impossible. 3/16 again is more popular.

Can you name the brands of similar (or better ropes), that are easy to purchase over here ? The ones I found are all weak.
