Look and see what other feet are available for your machine. I have a 'ruler' foot that has an industry standard size circular foot that you use with rulers (I think there are 2 sizes of these feet, your machine will use one or the other. Mine is the 1/2" one, but I think the high end machines are 5/8". This allows you to use LONG ARM guides (not rotary cutting rulers or templates) with your machine. I also have an open toe foot that lets me see what the heck I'm doing for free motion work. I'm partial to DeLoa Jones' guides:

her arc guides have an 'innie' and 'outie' side the same circumfrence so you can use it on the left or right.
As stated in the other post, you also need to get a guide table for your machine. This extends the size of the stitching base on your machine so you can safely use the templates. The down side is that this will cut down on the amount of quilting space you have as the base will hit the sides and front of your frame a bit. It's well worth the inconvenience.
