Fly Boxes

As jeff miller and others know, I tend to get wet when I fly fish. I
take chances when I shouldn't and often get my fly boxes immersed.
This means I have to dry them out, and even then, some of the flies
rust. I don'[t mind getting wet, but it kills me when my flies do.

I have used Wheatley boxes in the past, as well as C&F and those cheap
foam boxes with the lids held together with 2 magnets. Everything I
have lets water in. However, I now see advertised the SA waterproof
fly box system. It has a rubber gasket which seals water out. They
could call if the Frank Reid Model, but I don't see Frank's name
mentioned in the ad. They are the right size and have inserts for
nymphs, dries, and streamers. Also available is a lightweight foam
insert storage suitcase which seems like a handy way to organize those
flies which you are not using.

Question: Has anyone tried this system, and if so, how is it?

What fly boxes *do* you use?
