The short story....What is the easiest way to finish a king size quilt? Birthing/pillowcase turning and tying? Is it easier to just tie and bind?

The long story....Have a fabulous family here that we do alot of stuff with. My friend has been searching for a comforter that she likes and can't find one. She was in the PX (were military, it's our local military store like a small walmart) and one of the shops outside the PX had some quilts. She found one she liked but it was over 300, she said the saleslady had told her it was hand done in Poland. She asked me to go look at it and tell her if it was worth it. She owns old quilts from her hubby's gran so she was looking for heirloom. I went yesterday and both my husband and I took one look and those are done fully by machine even the binding and done with thin cheap fabrics.....salespeople should not lie about something like that. So because were really good friends I told her if she wanted I would take her online and we would look at fabrics and clearance fabrics and see what we could find and it was an investment and I would help her make a quilt for her bed. I'm going to use an easy quick pattern so I'm wondering what the easiest way to finish it? My machine can't handle a king size to FMQ. So I thought tying would give her not only the look she's after but easy and quick to do. What method for that size has more success.....birthing or binding?
