corbind gets his hardware store grommets for less than 30 cents. The two-pack of Sampras dampeners is priced at $3....so it's like a 5 for 1 situation.
The rubber grommets dampen more being all rubber (and contacting a little more string) and not a plasticy silicone material of the Sampras dampener.
Again, it's a preference thing.
