Scratchie, I agree with you totally, you've hit the nail on the head. The higher range of machines which have come out in the last 10 yrs or so aren't reliable like mum's old treadlie, and I know several who've bought lemons, and the most expensive machines. I've had 3 Brothers, sold the oldest and still have a 3000 and 4000, which I got nearly halfprice. One preloved, and one sellout because of new models coming out. I find they are so user-friendly compared to other brands, and still use the same format for embroidery designs [pes] whereas other brands change theirs. I've had no problems with any of them, but do get one that uses larger hoops. If you love embroidery a 4x4" hoop will quickly wear thin.
Good luck
