I always check the tables owners manual to make sure I have the original factory headshell for that exact model, some headshells were used on a number of models and some are specific to one or two tables and not all as pictured weigh the same. Hifido usually has a good selection of headshells and the weight is listed. Also be aware when shopping on Ebay and elsewhere for headshells described as Technics "like", these are cheap knockoffs and many times have flaws, also outright counterfits being sold.
