What a great husband! Okay now take a deep breath and remember to keep breathing.
I have had Berninas (several different ones) for years and yes I Love them. The needle threader takes some practice, but don't give up. It is like the knee lift (hands free) when I got my first Bernina I thought what in the heck is this, and it seemed like it took me months to get used to but now - if I have to sew without it I swear my finger gets sore from lifting the presser foot, especially when I am quilting. The needle threader does also take some practice and I will warn you that it can get out of alignment although I think the newer ones are a little sturdier than what is on my older machine.
In addition to your dealer please also check out the Bernina USA website - they have a ton of stuff out there
Here's to you and your new Bernina - I know you will have many happy times together
