I was just looking around to see what is a good cooktop and found some comparison and this brand BlueStar is interesting. Does this model RBCT365BSSV2 worth the money? Around $2,400 or so. It is open top and some videos said that it is easy to clean which look ok but I wonder how to clean the center part which is not removable or that nothing really is going to be on it. I never bought this type of appliance before so I am not sure what to look for except BTU and cleaning.
