Will it be worth it financially? Probably not, but you could use it simply as a personal advancement, or in a couple years to renew your CFI ticket. I finally let my CFI laps last year, but I'm thinking about getting my MEI to renew it. All I should have to do is alittle brushing up on the books and the ride, since I already far exceed the mins. So I'd imagin I should be able to do it under $500, maybe.
