I have the Westalee Ruler foot with 9 different templates, and have had a lot of fun with them. I made a sampler to help sell them at the store where I work, and have been teaching classes with them. Here's a picture of my sampler. I hope the stitching will show up OK.
Also wanted to add that when you buy the Westalee templates from your LQS, the retail on them is $75 for the foot with 2 templates, and $75 for the starter set that has 6 templates. Plus there are 2 catalogs full of different templates you can buy separately.
