Thank you
@Celia, actually I can use a foot control just to press down, it's the finer movements of controlling speed that is a problem, so it would suit me (if I had £3k+!)
@realale, I didn't mean to hijack your thread, I hope you've found this discussion useful.
I do like my 14 year old Janome 6234XL. It does everything I want of it, although I no longer do hems (because of controlling speed). For seams and stitching edges, it keeps tension well and copes with different weights of fabric well.
