Love all the features of the kayfun but bought subtank --topbox mini and lemo2 clone. The subtanks were too airy but now with the rebuildables install i tend to like them for creamy or custard juices and the kayfun 4 for fruits. The lemo clone is horrible.Anyways is there a tank no airier than the subtank mini with all of the features (top fill--juice control and coil change with no juice loss} of the KF4 ? thanks
