Year one as agent costs nothing; every later year is $149, in any state.
Over three years it costs $100 more than Registered Agent MS.org, and for us the extra things it handles are worth that.

How we scored these
Here's how we scored it: three-year cost and filings in the price are worth 29% each, and renewal price, state fit and up-front totals split the other 42%. In Mississippi, filings in the price made the difference.
Registering in a second state means working with two states, so one company at one price for both won the coverage score over Registered Agent MS.org.
