HI One thing missing from the list was the HP 53181. It's useless as a timing device and thus didn't get listed. If you are after frequency only, they occasionally show up for quite a bit less than the 53131's. As a frequency counter, they have the same performance as a '131. All of the 53131, 132, 181, and 230's are small enough to lug around.
