Yes you are right , the price of the models depends on the brand, and the two most common brands that come to Pakistan are MAISTO and Bburago, thats why i quoted the above prices .
Rs 15000 and plus , now these are high detailed models made by AutoARt , Tamiya , Kyosho , EBbro , and so on , which we donot find it in Pakistan .
Rs 20000 and plus , now these are models that are made by model builders which is available in the form of kits , and these models are made to order , and are very expensive.
