I have a 1/4" foot also, but it's just a hassle taking my walking foot off; so I have figured out where the 1/4" is on the walking foot, now I use it for EVERYthing.
Why can't they just make the regularly feet with "teeth" on the bottom so they can grab the materials too? (I'm too simple-minded :))

I got the 1/4 inch foot with my Bernina, and bought the walking foot, and don't know how I survived without both of them. You will never be sorry about either purchase. I can't afford LAQ, so the walking foot was a good investment, since I do all my own quilting, mostly SID or just outside the seam line, is that called shadow quilting? Anyway, go for it,

They are really good for table runners, pot holders, SITD quilting, cross hatching, making bags. very handy, couldn't live without mine

Must have's...yes

A 1/4" foot is on my machines as the everyday foot.
I don't machine quilt often, but when I do I always use the walking foot. Didn't once and the results were not good.

Both are invaluable. If you only purchase 2 machine items, these are the 2.

I would get both if you can. You'll see the difference right away with the 1/4 foot.

A walking foot is GREAT for garment sewing too. Hemming t-shirts has always been troublesome for me, but this time I used the walking foot and what a difference! No more hem ripples. Also great for pile fabrics and matching plaids. Just would say not to sew too fast.

Both! Both! BOTH!!'

I use both of mine all the time. The walking foot is a must. I am able to quilt my quilts on a LA but need my walking foot to put the binding on. I love love love my 1/4" seam foot. I can't say enough good things about it.
