I bought their Prep-Tool and Seam Guides and love them! Their Prep-Tool allows you to place their Seam Guides a scant 1/4" from your needle. I think their prices are very reasonable. I prefer their Seam Guides over any other item as they are very nice looking and leave no sticky residue. I've been using their tools for a few years now. I did have their rulers but gave them to a gal here on the board.
