I think the bigger problem with FRIs now is that it comes out of the money devolved to the Single Service. Previously the sS applied to the Treasury/MoD for extra money, now they have to fund it out of their own pot. So, the question for CAS is, what you are going to sacrifice to afford the FRI? The type of money people have been mooting on here are about equivalent to 2 or 3 Junior Ranks' annual salary (at least). Are you prepared to stand up to The Sun (or Defence Select Committee) and say you're worth that?
