My Viking has a scant 1/4 setting for the needle. I love it. I purchased a 1/4" foot with the guide and it measured larger than 1/4" so just make sure if you do purchase one of these that you are able to return it if you don't like it. My dealer is very nice and took it back no problem. I find that the needle position on my machine is best for me. Prior to having this machine, the old White mechanical machine I had, I used one of the magnetic seam allowance guides. Great tool, imo, if you can use it on your machine. Same principal as using a stack of post-it's; moleskin; index card, etc. but it STICKS on that bed and you can easily re-position it for any type sewing you may be doing.
