When my husband told me I could get the machine of my dreams, I went right to the Janome dealer and when she asked how much I wanted to spend, I said $1200 because that was the most outlandish number I could imagine. I ended up spending every cent of that $1200, but I've never regretted it.
My machine sews SO smoothly, is set up for sensible ergonomics, and has just been making me smile every time I look at it for 2 years.
I miss my old Singer, which I had for over 20 years, but the gears inside were plastic and the repair guy told me it would cost as much to replace them as to buy a similar machine. My friend, a professional quilter, has raved about her Janome machines (yes, plural!) so after trying a few out, I picked mine.
I would say try several machines, different brands, and see what suits you!
HAPPY STITCHING!!
