I have a Komelon that I got at Lowes and it is a great tape. It is just the oppsite of most tapes in that when you pull it out it stays until you push the button, most tapes you have to push a button of some type to lock the tape.
This is really nice, you pull it out to measure a board or mark you cut points and it stays there until you push the button.
I also have the Fastcap black and it is flat and has the marks just on one edge, the other edge is just white and you can mark on it, nice to use as a story stick.
