disagree .. price depends on the make of cylinder.
Ladi renzo kit with advancer and emulator have almost fixed price at every retailer. Its only the cylinder make and capacity which alters the total cost.
If you go for a less known EKC cylinder 55 kg- the total cost would be between 32-35000rs.
If you want a well known cylinder for example faber, or cylbrass the price will increase by 10000rs.
Price of landi kit is not different no matter where you go to get it fitted.
So if you go for landi renzi kit plus advancer and emulator and 55 kg EKC cylinder--- 32-35K total cost including fitting.
If you go for italian brand cylinder like faber or cylbrass plys the ladi renzo kit plus landi renzo advancer emulator--- total price would be between 42-45K including fitting.
Its up to you now whether you want cylinder from a less known brand or well known brand like faber.
