Congratulations on the gift certificate. I would agree with the majority of the replies to this post, a chrony is a very nice tool to own and because the lions share of the money is not coming out of your pocket, its a nice little luxury item (also practical). The only other item on your list I would buy with a gift certificate is the trim mate. Its a very handy tool, saves a lot of time, and saves wear and tear on your wrists and fingers. When my trim mate burns out years from now, Ill waste no time replacing it.
