Catsden..i have the sure foot which I am just now quilting my first quilt with. So far I love it as it has higher edges so you can't run over the rulers as I did when i quilted my last quilt. It was a constant battle with my last quilt without the sure foot as I had thicker batting and fleece as backing and no matter how hard i tried the ruler kept slipping into the needles path.
I asked around before i bought mine and everyone i asked said it was worth the money.
I have fleece backing on this quilt and not once have I had a ruler slip into the needles path. I definitely recommend it.

I went to youtube to see a demo of the sure foot because I was curious also. https://www.youtube.com/watch?v=QdV07BQM-fw

Just quilted my first quilt using the surefoot. I really liked it when I used my rulers. It does make threading the machine a little harder, but would recommend it.

I have watched the install demo. Looks to be not to hard. Did anyone have trouble changing out to the sure foot? The kit is 99.95 but you get a couple of other feet with it. The sure foot is 59.95. Will still get it though.

I have the sure foot especially after I did crunch a ruler and for me, I feel more confident and therefore it was worth the money to me. My S16 had a fixed foot (one that a tech would have to change) so I needed to buy the feet conversion kit. Now I use other feet easily.

I purchased the sure foot and it works great especially for ruler work. I tried without it and my ruler slipped under the foot and jammed the whole machine causing a trip to the dealer to have it fixed. Totally worth the price

I had to convert my foot, and it was not a big deal at all - however I routinely do work on vintage machines so am very use to taking parts off and putting them back on.

I also have the glide foot (favorite) along with the echo and couching feet, though I've not used the couching feet yet. I love having the ability to swap feet based on the type of quilting I'm doing.
