Thank you for your advice, Prism!
The demo went very well. I enjoyed using the machine, I had no problem with threading or changing feet (or anything, really), and I fell in love. The dealer was also extremely kind, patient, and happy to explain every little thing I could think to ask. What a wonderful experience! And I know from searching this board that $1000 for the machine and all relevant attachments/parts/accessories was a price that couldn't be beat.
I just wish I could be home playing with her right now instead of working until 10PM!
