So very sorry to hear about your loss! The smash and grabs are the worst because they have no idea of the value of what they get their hands on.
All three of my machines are Elnas. Two were purchased before Janome and Elna joined and I have purchased the top of the line sewing and embroidery machine that has been manufactured since their "merger". I love all three of them and I do not think the quality has suffered since the "merger". I do think you have to purchase from a dealer who offers service and education after the sale though. I have sewn on the 6600 and it is a great machine. All the accessories store right on the front of the machine in their own slots and are covered by a door. The newest Elna for quilting, the e740, is the best though. I have test driven it several times and am absolutely in love! I am saving up for it.
Good luck on your search. I will keep my eyes open here in Kansas for your possessions!
