It looks to me that the price of a decent hanger from major US sellers is way above the budget you are looking at. The $30 cost before shipping is higher than the up to 100RM you don’t want to pay locally ($30 seems to be about 120 RM).
I understand that money is important, but in this case some of the money you would pay a local shop goes towards the expertise they hold and the risk that they take. Let’s say you order internationally and pay money + shipping + tax and find out it doesn’t quite fit the bike, you’ll be losing money. If the shop takes the risk of ordering the part, your money is safe until they fit the correct part.
I think that the 5RM ($1.22) price point you are looking for will be alien to most US,euro,aussie etc users here, but maybe someone cleverer than me will know how to search more locally to Malaysia and can be more helpful.
CSU’s answer seems to identify the hanger, but if you can’t find one matching on local websites for the price you want to pay then my answer is sorry you’ll have to accept and pay for, the expertise of your local shop.
