I can't really say what machine for a 1/4 inch seam without a price range. My Bernina 440 does a great 1/4 inch seam with the #37 foot as others have stated. It cost about $2,900 to buy this year. The price is probably going to go down as I've heard it is going to be discontinued? If you have a good sewing machine dealer where you are, bring a piece of 1/4 inch graph paper with you to try out their machines and see what works best. The reason it is best to check your area is so you have support for learning your machine and for repairs and cleaning.
