I got a refurb Voyager in November. (I use it on my Bernina frame) I do love it. :-)
I am really happy with the condition of my unit, it looked like new.
If you are not sure about FMQ on a frame, you could get just the frame and try it with your regular sewing machine. You will know pretty quickly if it is for you! (I knew right away that I love having a frame!)
Also, be aware that the quilts frames are HUGE. mEASURE YOUR space.
