Elna is now made by Janome. So the Elna 740 eXcellence is the Elna version of the Horizon by Janome, and the 7300 Quilting Queen is the Elna version of the Janome 6600. Few different stitches, but same basic machines, both with Accufeed. The 7300/6600 don't have free arms. The possible + for you with Janome/Elna might be the drop-in bobbin, if a vertical bobbin is tricky because of your arthritis. Bernina's walking foot us very easy to install and remove, btw. No screws.
