Cheap good underwater/waterproof cases?

[combat squirrel]

As title really, looking for a case for summer for my FujiFilm F40fd to allow me to take it to the beech, take pics on beech, and take in the water to muck around with (defo wont be diving with it)

I looked at the offical case, was £129 :S, wayy to much as im not diving

After much searching found this:

the DiCAPac case, about £20 delivered, think it would do the job ? (light swimming in sea with it, mayb -just- under the water to take -some- pics, mostly just getting splashed etc on the surface)

I cant find anything similar in the UK though, any ideas?

Thanks

Don't think I'd be trusting a plastic bag keeping my camera dry under the water unless it was a proper case. Try http://www.camerasunderwater.co.uk/ see if they can help you out. My son is commercial diver and uses this firm quite a lot. He say's their quite a helpful bunch.

Yeah its more for messing on the coast than actually being underwater for any length of time, hence why a 40M waterproof case may be overkill
