Best recommendations for repricers

I’m looking for a repricer that can automate keeping up with the featured buy box price, but also if the buy box goes away on the same ASIN, will drop to the lowest price by 1 penny all in one repricer tool. Amazons automated price tool isn’t the best and doesn’t really distinguish a reliable “lowest price” and will just do the account with the lowest price, even if they don’t have free shipping. I want to only compete with sellers with the same shipping settings as me or similar (ie not the accounts with “free shipping with $35 or more”)
