We went with IKEA for our kitchen remodel and saved a lot of money putting it all in ourselves. However, when it came time to install the handles on the cabinets, I tried carefully measuring the first one I did and it did not work very well. Then I found IKEA sells a drill template for just this purpose, it makes it trivial to install handle after handle in the same spot each time, and the handles came out great. The drill template aligns with one side of the cabinet door and you can mark and drill in seconds. I used a Sharpie to circle the holes that I was marking to make it even easier to know which holes in the template I was using.
