Only remember one thing brother. Follow some basic rules in buying any thing in the world. There are some standards which are pre set and have a background with some significant history. I dont argue on the people who try new things but following the stander is never a failure. These local brands as you named are totally rubbish. They have have low quality frame, structures, engine and body parts. One you purchase them, you have opened an account for the mainitaince with them.
Always follow the standars.
