Hi Sheri, Thanks for clearing that up. I just assumed that the Eclipse and the PEC pads were the same, that is, I thought both were a complete swab. That seems to make more sense with respect to the price difference. I also agree, particularly with the stress surrounding my first attempt at cleaning the sensor on my D700, I really didn't need to add to it by making up the swab.
Also, the risk of contaminating the swab with your own skin oils is something that needs serious consideration in the "make your own" versus "buy already made" type. You really have to make sure you've scrubbed properly before you attempt this.
