The only place in SLT that I found decent quality knobs is the one store in the basement at the end of the hallway, close to the exit that seems to sell mostly refurbished things. However, I recently entered a shop on Jalan Besar almost at the height of Mustafa which was actually overflowing with gazillions of knobs and nothing else. I will find out the name when I'm in the area next time.
