I've used the same Super Agata for about 10 years. Had to replace the bell recently after using crown caps on champagne bottles. The lip on the champagne bottles was to large and deformed the bell. Replacement bells are available in 26 mm and 29 mm sizes. Previous to this used an adjustable cast iron bench capper that was used to cap soda bottles during the prohibition period.
Never used a wing capper but can imagine how awkward and tedious they are to use.
The newer model Super Agata is easier to adjust for different bottle heights.
