I have a 4 burner Faber hob , 5yrs old. The burners are of brass n aluminium . The gap developed between the brass n aluminium and the flame is lost through the gap, technician is saying they are imported burners hence each will cost Rs2500/- n Have to replace all four burners. Rather than spending 10000/- on burners I feel it's better to change the burner itself. The carcass size is 60 x47cm. Can you suggest a good hob with economical burners that fits the granite cutout. Around 65x50cm dimensions
