Which brand wet grinder has high durability ?

I have a Crompton Greaves Brand grinder that I bought from Trade Fair 2001. It's still working fine. What we have spent after we bought it in its jars especially the washers and spindles. The motor is still okay and noiseless.  

I cannot say which is the best brand, but there are quite a few. Butterfly, Usha, Prestige & Preethi are some of the Indian ones. Havells, Panasonic are some of the well know ones too.
