Our favorite is Mainstay Filing, because it's $199 beyond the state fee in any state, and the first resident agent year is included.
Your free agent year ends after twelve months, and then it's $149 a year in any state.
Over three years it costs $100 more than KS Registered Agent.org, and for us the extra things it handles are worth that.

What decided the order
LLC Review Desk gives three-year cost 29% and filings in the price 29%, then divides 42% among renewal price, state fit and up-front totals. For Kansas, it came down to filings in the price.
Registering in a second state means working with two states, so one company at one price for both won the coverage score over KS Registered Agent.org.
