On second thought, I'd like to recommend the Silent Timer.

Just a heads up: a few days before the Feb LSAT, I got this email from Powerscore regarding the Silent Timer:
"Recently, you purchased a Deluxe Silent Timer from us. This afternoon we were notified by the manufacturers of that timer that Law Services, the maker of the LSAT, has advised that they may disallow that product for in-test use, and may not allow some students to use that timer on test day. While past history suggests that most students will not have an issue using the Deluxe Silent Timer during the test, we understand that some students might be concerned about possible problems..."
BTW, Powerscore overnited me a "Basic Timer" at NO COST whatsoever, which I thought was very big of them (I had to shove my brains back in my ears when I got this email just a few days before the test) Nevertheless, the features on the Deluxe Silent Timer are incomparable for studying and improving timing (see their website). Other than a chance siting on ebay, Powerscore had the best price for the Silent TImer, and if it's true they're now disallowed, I bet the price will come down even further as they attempt to purge inventory.
I brought both timers to the test (Basic as backup), but the Silent Timer was not confiscated (since it was less than a week of the LSAC notification, could it be the Proctors were just not aware yet?)
Thought you all should know.
