Here's something else to consider: mobility!
The first floor frame I bought consists of two sturdy adjustable ends that accommodate 3 poles of whatever length I want to use. I bought (for a king sized quilt) the longest and straightest poles that I could find at the lumber store. At that time, I planned in future to buy shorter sets of poles for smaller quilts, but I never got to that point before I dismantled the frame and stored it away.
Because I am right handed, I can sew accurately and speedily from right to left, am mediocre going up or down, but it is barely possible for me to sew from left to right ... I am slow with it and still have a lot of do-overs.
I now hand-quilt using no frame or hoop ... the only requirement is that the quilt sandwich layers be firmly secured together. It is so liberating not to have any hoop or frame at all to get in my way. No re-hooping and no more trying to sew from left to right. I just love it. My speed and accuracy have much improved as well as my comfort level.
I'm not suggesting that this method is for you ... what I am suggesting is that you choose something that allows you freedom to sew in all directions.
