I haven't tried a snipe program. I just set my highest bid and wait for notification. Sometimes I get lucky.
I find a snipe program removes all the emotion, and forces me to forward set a price I can live with.
I used Auction Sentry for years, however they became very money hungry trying to upgrade frequently, and lately I am using Auction Defender, which works well.
Most of the snipe programmes offer a 30 day trial, its worth using, and once you do I'm sure the value is seen.
BTW, I love the bracelet on that watch, very nice.
