I have a Brother PQ-1500 that I actually purchased to use for fmq only..But I notice I use it a lot for piecing, and regular sewing, too It has a pin-feed system that makes piecing a breeze! It is all metal, and does straight stitch only...has knee-lift, auto thread cut, and a 9" harp. I also have a Brother PC-420, which I love, it is my go to for all the "fancier" stitches...it also has the knee-lift and auto thread cut. I love them both for different reasons. Paid under $600.00 for the 1500. and under $500.00 for the 420. I also have my great grandma's Singer 66, my dh is currently giving it a good cleaning...I have the original cabinet it came with, too. It is a treadle machine, but "Ma" had a motor put on it, too...I used to always buy Singers prior to the 2 Brothers, but the last 2 Singers I had purchased just didn't measure up like the used to...my opinion only, and we all know how that goes...lol...
