Anyone have any experience with these brackets? I have about 8 which have broken because they are made of die cast cheese metal. Went to mastercraft kitchens where the drawers are from and they said the part is no longer available (of-course it isn't), they can supply me with a new part but it has a different fitting (of-course it does) which means I have to replace the whole side panel of the drawer as well (intentional?), cant remember exact figures but this ends up costing somewhere around $80 + gst per drawer if I do the work myself. 

I don't feel like spending nearly half a grand just to fix some stupid brackets, anyone had this problem before, any ideas, or sources of cheap replacement brackets? I have seen generic brackets on ebay but profile looks different. Photo above is not the exact bracket, just generic image so you know what I am talking about
